1  518 143 COMPARING ONCE- VERSUS TWICE-WEEKLY YOGA CLASSES FOR CHRONIC LOW BACK PAIN IN PREDOMINANTLY LOW INCOME MINORITIES: A RANDOMIZED DOSING TRIAL. BACKGROUND. PREVIOUS STUDIES HAVE DEMONSTRATED THAT ONCE-WEEKLY YOGA CLASSES ARE EFFECTIVE FOR CHRONIC LOW BACK PAIN (CLBP) IN WHITE ADULTS WITH HIGH SOCIOECONOMIC STATUS. THE COMPARATIVE EFFECTIVENESS OF TWICE-WEEKLY CLASSES AND GENERALIZABILITY TO RACIALLY DIVERSE LOW INCOME POPULATIONS ARE UNKNOWN. METHODS. WE CONDUCTED A 12-WEEK RANDOMIZED, PARALLEL-GROUP, DOSING TRIAL FOR 95 ADULTS RECRUITED FROM AN URBAN SAFETY-NET HOSPITAL AND FIVE COMMUNITY HEALTH CENTERS COMPARING ONCE-WEEKLY (N = 49) VERSUS TWICE-WEEKLY (N = 46) STANDARDIZED YOGA CLASSES SUPPLEMENTED BY HOME PRACTICE. PRIMARY OUTCOMES WERE CHANGE FROM BASELINE TO 12 WEEKS IN PAIN (11-POINT SCALE) AND BACK-RELATED FUNCTION (23-POINT MODIFIED ROLAND-MORRIS DISABILITY QUESTIONNAIRE). RESULTS. 82% OF PARTICIPANTS WERE NONWHITE; 77% HAD ANNUAL HOUSEHOLD INCOMES <$40,000. THE SAMPLE'S BASELINE MEAN PAIN INTENSITY [6.9 (SD 1.6)] AND FUNCTION [13.7 (SD 5.0)] REFLECTED MODERATE TO SEVERE BACK PAIN AND IMPAIRMENT. PAIN AND BACK-RELATED FUNCTION IMPROVED WITHIN BOTH GROUPS (P < 0.001). HOWEVER, THERE WERE NO DIFFERENCES BETWEEN ONCE-WEEKLY AND TWICE-WEEKLY GROUPS FOR PAIN REDUCTION [-2.1 (95% CI -2.9, -1.3) VERSUS -2.4 (95% CI -3.1, -1.8), P = 0.62] OR BACK-RELATED FUNCTION [-5.1 (95% CI -7.0, -3.2) VERSUS -4.9 (95% CI -6.5, -3.3), P = 0.83]. CONCLUSIONS. TWELVE WEEKS OF ONCE-WEEKLY OR TWICE-WEEKLY YOGA CLASSES WERE SIMILARLY EFFECTIVE FOR PREDOMINANTLY LOW INCOME MINORITY ADULTS WITH MODERATE TO SEVERE CHRONIC LOW BACK PAIN.

2 2852  65 YOGA, PHYSICAL THERAPY, OR EDUCATION FOR CHRONIC LOW BACK PAIN: A RANDOMIZED NONINFERIORITY TRIAL. BACKGROUND: YOGA IS EFFECTIVE FOR MILD TO MODERATE CHRONIC LOW BACK PAIN (CLBP), BUT ITS COMPARATIVE EFFECTIVENESS WITH PHYSICAL THERAPY (PT) IS UNKNOWN. MOREOVER, LITTLE IS KNOWN ABOUT YOGA'S EFFECTIVENESS IN UNDERSERVED PATIENTS WITH MORE SEVERE FUNCTIONAL DISABILITY AND PAIN. OBJECTIVE: TO DETERMINE WHETHER YOGA IS NONINFERIOR TO PT FOR CLBP. DESIGN: 12-WEEK, SINGLE-BLIND, 3-GROUP RANDOMIZED NONINFERIORITY TRIAL AND SUBSEQUENT 40-WEEK MAINTENANCE PHASE. (CLINICALTRIALS.GOV: NCT01343927). SETTING: ACADEMIC SAFETY-NET HOSPITAL AND 7 AFFILIATED COMMUNITY HEALTH CENTERS. PARTICIPANTS: 320 PREDOMINANTLY LOW-INCOME, RACIALLY DIVERSE ADULTS WITH NONSPECIFIC CLBP. INTERVENTION: PARTICIPANTS RECEIVED 12 WEEKLY YOGA CLASSES, 15 PT VISITS, OR AN EDUCATIONAL BOOK AND NEWSLETTERS. THE MAINTENANCE PHASE COMPARED YOGA DROP-IN CLASSES VERSUS HOME PRACTICE AND PT BOOSTER SESSIONS VERSUS HOME PRACTICE. MEASUREMENTS: PRIMARY OUTCOMES WERE BACK-RELATED FUNCTION, MEASURED BY THE ROLAND MORRIS DISABILITY QUESTIONNAIRE (RMDQ), AND PAIN, MEASURED BY AN 11-POINT SCALE, AT 12 WEEKS. PRESPECIFIED NONINFERIORITY MARGINS WERE 1.5 (RMDQ) AND 1.0 (PAIN). SECONDARY OUTCOMES INCLUDED PAIN MEDICATION USE, GLOBAL IMPROVEMENT, SATISFACTION WITH INTERVENTION, AND HEALTH-RELATED QUALITY OF LIFE. RESULTS: ONE-SIDED 95% LOWER CONFIDENCE LIMITS WERE 0.83 (RMDQ) AND 0.97 (PAIN), DEMONSTRATING NONINFERIORITY OF YOGA TO PT. HOWEVER, YOGA WAS NOT SUPERIOR TO EDUCATION FOR EITHER OUTCOME. YOGA AND PT WERE SIMILAR FOR MOST SECONDARY OUTCOMES. YOGA AND PT PARTICIPANTS WERE 21 AND 22 PERCENTAGE POINTS LESS LIKELY, RESPECTIVELY, THAN EDUCATION PARTICIPANTS TO USE PAIN MEDICATION AT 12 WEEKS. IMPROVEMENTS IN YOGA AND PT GROUPS WERE MAINTAINED AT 1 YEAR WITH NO DIFFERENCES BETWEEN MAINTENANCE STRATEGIES. FREQUENCY OF ADVERSE EVENTS, MOSTLY MILD SELF-LIMITED JOINT AND BACK PAIN, DID NOT DIFFER BETWEEN THE YOGA AND PT GROUPS. LIMITATIONS: PARTICIPANTS WERE NOT BLINDED TO TREATMENT ASSIGNMENT. THE PT GROUP HAD DISPROPORTIONATE LOSS TO FOLLOW-UP. CONCLUSION: A MANUALIZED YOGA PROGRAM FOR NONSPECIFIC CLBP WAS NONINFERIOR TO PT FOR FUNCTION AND PAIN.

3 2560  50 YOGA FOR CHRONIC LOW BACK PAIN: A RANDOMIZED TRIAL. BACKGROUND: PREVIOUS STUDIES INDICATE THAT YOGA MAY BE AN EFFECTIVE TREATMENT FOR CHRONIC OR RECURRENT LOW BACK PAIN. OBJECTIVE: TO COMPARE THE EFFECTIVENESS OF YOGA AND USUAL CARE FOR CHRONIC OR RECURRENT LOW BACK PAIN. DESIGN: PARALLEL-GROUP, RANDOMIZED, CONTROLLED TRIAL USING COMPUTER-GENERATED RANDOMIZATION CONDUCTED FROM APRIL 2007 TO MARCH 2010. OUTCOMES WERE ASSESSED BY POSTAL QUESTIONNAIRE. (INTERNATIONAL STANDARD RANDOMISED CONTROLLED TRIAL NUMBER REGISTER: ISRCTN 81079604) SETTING: 13 NON-NATIONAL HEALTH SERVICE PREMISES IN THE UNITED KINGDOM. PATIENTS: 313 ADULTS WITH CHRONIC OR RECURRENT LOW BACK PAIN. INTERVENTION: YOGA (N = 156) OR USUAL CARE (N = 157). ALL PARTICIPANTS RECEIVED A BACK PAIN EDUCATION BOOKLET. THE INTERVENTION GROUP WAS OFFERED A 12-CLASS, GRADUALLY PROGRESSING YOGA PROGRAM DELIVERED BY 12 TEACHERS OVER 3 MONTHS. MEASUREMENTS: SCORES ON THE ROLAND-MORRIS DISABILITY QUESTIONNAIRE (RMDQ) AT 3 (PRIMARY OUTCOME), 6, AND 12 (SECONDARY OUTCOMES) MONTHS; PAIN, PAIN SELF-EFFICACY, AND GENERAL HEALTH MEASURES AT 3, 6, AND 12 MONTHS (SECONDARY OUTCOMES). RESULTS: 93 (60%) PATIENTS OFFERED YOGA ATTENDED AT LEAST 3 OF THE FIRST 6 SESSIONS AND AT LEAST 3 OTHER SESSIONS. THE YOGA GROUP HAD BETTER BACK FUNCTION AT 3, 6, AND 12 MONTHS THAN THE USUAL CARE GROUP. THE ADJUSTED MEAN RMDQ SCORE WAS 2.17 POINTS (95% CI, 1.03 TO 3.31 POINTS) LOWER IN THE YOGA GROUP AT 3 MONTHS, 1.48 POINTS (CI, 0.33 TO 2.62 POINTS) LOWER AT 6 MONTHS, AND 1.57 POINTS (CI, 0.42 TO 2.71 POINTS) LOWER AT 12 MONTHS. THE YOGA AND USUAL CARE GROUPS HAD SIMILAR BACK PAIN AND GENERAL HEALTH SCORES AT 3, 6, AND 12 MONTHS, AND THE YOGA GROUP HAD HIGHER PAIN SELF-EFFICACY SCORES AT 3 AND 6 MONTHS BUT NOT AT 12 MONTHS. TWO OF THE 157 USUAL CARE PARTICIPANTS AND 12 OF THE 156 YOGA PARTICIPANTS REPORTED ADVERSE EVENTS, MOSTLY INCREASED PAIN. LIMITATION: THERE WERE MISSING DATA FOR THE PRIMARY OUTCOME (YOGA GROUP, N = 21; USUAL CARE GROUP, N = 18) AND DIFFERENTIAL MISSING DATA (MORE IN THE YOGA GROUP) FOR SECONDARY OUTCOMES. CONCLUSION: OFFERING A 12-WEEK YOGA PROGRAM TO ADULTS WITH CHRONIC OR RECURRENT LOW BACK PAIN LED TO GREATER IMPROVEMENTS IN BACK FUNCTION THAN DID USUAL CARE.

4  258  40 ACCEPTABILITY AND FEASIBILITY OF A 12-WEEK YOGA VS. EDUCATIONAL FILM PROGRAM FOR THE MANAGEMENT OF RESTLESS LEGS SYNDROME (RLS): STUDY PROTOCOL FOR A RANDOMIZED CONTROLLED TRIAL. BACKGROUND: RESTLESS LEGS SYNDROME (RLS) IS A COMMON AND BURDENSOME SLEEP DISORDER ASSOCIATED WITH PROFOUND IMPAIRMENT OF HEALTH, WELL-BEING, AND QUALITY OF LIFE. UNFORTUNATELY, THE MEDICATIONS USED FOR RLS MANAGEMENT CARRY RISK OF SERIOUS SIDE EFFECTS, INCLUDING AUGMENTATION OF SYMPTOMS. YOGA, AN ANCIENT MIND-BODY DISCIPLINE DESIGNED TO PROMOTE PHYSICAL, EMOTIONAL, AND MENTAL WELL-BEING, MAY OFFER A VIABLE, LOW-RISK NEW TREATMENT. THE PRIMARY OBJECTIVES OF THIS PILOT, PARALLEL-ARM, RANDOMIZED CONTROLLED TRIAL (RCT) ARE TO ASSESS THE ACCEPTABILITY AND FEASIBILITY OF A 12-WEEK YOGA VS. EDUCATIONAL FILM PROGRAM FOR THE MANAGEMENT OF RLS. METHODS: FORTY-FOUR ADULTS WITH CONFIRMED MODERATE TO SEVERE RLS WILL BE RECRUITED AND RANDOMIZED TO A 12-WEEK YOGA (N = 22) OR STANDARDIZED EDUCATIONAL FILM PROGRAM (N = 22). YOGA GROUP PARTICIPANTS WILL ATTEND TWO 75-MIN IYENGAR YOGA CLASSES PER WEEK FOR THE FIRST 4 WEEKS, THEN ONE 75-MIN CLASS PER WEEK FOR THE REMAINING 8 WEEKS, AND WILL COMPLETE A 30-MIN HOMEWORK ROUTINE ON NON-CLASS DAYS. EDUCATIONAL FILM GROUP PARTICIPANTS WILL ATTEND ONE 75-MIN CLASS PER WEEK FOR 12 WEEKS AND COMPLETE A DAILY RLS TREATMENT LOG; CLASSES WILL INCLUDE INFORMATION ON: RLS MANAGEMENT, INCLUDING SLEEP HYGIENE PRACTICES; OTHER SLEEP DISORDERS; AND COMPLEMENTARY THERAPIES LIKELY TO BE OF INTEREST TO THOSE PARTICIPATING IN A YOGA AND SLEEP EDUCATION STUDY. YOGA AND TREATMENT LOGS WILL BE COLLECTED WEEKLY. FEASIBILITY OUTCOMES WILL INCLUDE RECRUITMENT, ENROLLMENT, AND RANDOMIZATION RATES, RETENTION, ADHERENCE, AND PROGRAM SATISFACTION. PROGRAM EVALUATION AND YOGA-DOSING QUESTIONNAIRES WILL BE COLLECTED AT WEEK 12; DATA ON EXPLORATORY OUTCOMES (E.G., RLS SYMPTOM SEVERITY (IRLS), SLEEP QUALITY (PSQI), MOOD (POMS, PSS), AND HEALTH-RELATED QUALITY OF LIFE (SF-36)) WILL BE GATHERED AT BASELINE AND WEEK 12. DISCUSSION: THIS STUDY WILL LAY THE ESSENTIAL GROUNDWORK FOR A PLANNED LARGER RCT TO DETERMINE THE EFFICACY OF A YOGA PROGRAM FOR REDUCING SYMPTOMS AND ASSOCIATED BURDEN OF RLS. IF THE FINDINGS OF THE CURRENT TRIAL AND THE SUBSEQUENT LARGER RCTS ARE POSITIVE, THIS STUDY WILL ALSO HELP SUPPORT A NEW APPROACH TO CLINICAL TREATMENT OF THIS CHALLENGING DISORDER, HELP FOSTER IMPROVED UNDERSTANDING OF RLS ETIOLOGY, AND ULTIMATELY CONTRIBUTE TO REDUCING THE INDIVIDUAL, SOCIETAL, AND ECONOMIC BURDEN ASSOCIATED WITH THIS CONDITION.

5  461  52 CHANGES IN PERCEIVED STRESS AFTER YOGA, PHYSICAL THERAPY, AND EDUCATION INTERVENTIONS FOR CHRONIC LOW BACK PAIN: A SECONDARY ANALYSIS OF A RANDOMIZED CONTROLLED TRIAL. OBJECTIVE: PERCEIVED STRESS AND MUSCULOSKELETAL PAIN ARE COMMON, ESPECIALLY IN LOW-INCOME POPULATIONS. STUDIES EVALUATING TREATMENTS TO REDUCE STRESS IN PATIENTS WITH CHRONIC PAIN ARE LACKING. WE AIMED TO QUANTIFY THE EFFECT OF TWO EVIDENCE-BASED INTERVENTIONS FOR CHRONIC LOW BACK PAIN (CLBP), YOGA AND PHYSICAL THERAPY (PT), ON PERCEIVED STRESS IN ADULTS WITH CLBP. METHODS: WE USED DATA FROM AN ASSESSOR-BLINDED, PARALLEL-GROUP RANDOMIZED CONTROLLED TRIAL, WHICH RECRUITED PREDOMINANTLY LOW-INCOME AND RACIALLY DIVERSE ADULTS WITH CLBP. PARTICIPANTS (N = 320) WERE RANDOMLY ASSIGNED TO 12 WEEKS OF YOGA, PT, OR BACK PAIN EDUCATION. WE COMPARED CHANGES IN THE 10-ITEM PERCEIVED STRESS SCALE (PSS-10) FROM BASELINE TO 12- AND 52-WEEK FOLLOW-UP AMONG YOGA AND PT PARTICIPANTS WITH THOSE RECEIVING EDUCATION. SUBANALYSES WERE CONDUCTED FOR PARTICIPANTS WITH ELEVATED PRE-INTERVENTION PERCEIVED STRESS (PSS-10 SCORE >/=17). WE CONDUCTED SENSITIVITY ANALYSES USING VARIOUS IMPUTATION METHODS TO ACCOUNT FOR POTENTIAL BIASES IN OUR ESTIMATES DUE TO MISSING DATA. RESULTS: AMONG 248 PARTICIPANTS (MEAN AGE = 46.4 YEARS, 80% NONWHITE) COMPLETING ALL THREE SURVEYS, YOGA AND PT SHOWED GREATER REDUCTIONS IN PSS-10 SCORES COMPARED WITH EDUCATION AT 12 WEEKS (MEAN BETWEEN-GROUP DIFFERENCE = -2.6, 95% CONFIDENCE INTERVAL [CI] = -4.5 TO -0.66, AND MEAN BETWEEN-GROUP DIFFERENCE = -2.4, 95% CI = -4.4 TO -0.48, RESPECTIVELY). THIS EFFECT WAS STRONGER AMONG PARTICIPANTS WITH ELEVATED PRE-INTERVENTION PERCEIVED STRESS. BETWEEN-GROUP EFFECTS HAD ATTENUATED BY 52 WEEKS. RESULTS WERE SIMILAR IN SENSITIVITY ANALYSES. CONCLUSIONS: YOGA AND PT WERE MORE EFFECTIVE THAN BACK PAIN EDUCATION FOR REDUCING PERCEIVED STRESS AMONG LOW-INCOME ADULTS WITH CLBP.	2020	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                 
6  521  58 COMPARING YOGA, EXERCISE, AND A SELF-CARE BOOK FOR CHRONIC LOW BACK PAIN: A RANDOMIZED, CONTROLLED TRIAL. BACKGROUND: CHRONIC LOW BACK PAIN IS A COMMON PROBLEM THAT HAS ONLY MODESTLY EFFECTIVE TREATMENT OPTIONS. OBJECTIVE: TO DETERMINE WHETHER YOGA IS MORE EFFECTIVE THAN CONVENTIONAL THERAPEUTIC EXERCISE OR A SELF-CARE BOOK FOR PATIENTS WITH CHRONIC LOW BACK PAIN. DESIGN: RANDOMIZED, CONTROLLED TRIAL. SETTING: A NONPROFIT, INTEGRATED HEALTH CARE SYSTEM. PATIENTS: 101 ADULTS WITH CHRONIC LOW BACK PAIN. INTERVENTION: 12-WEEK SESSIONS OF YOGA OR CONVENTIONAL THERAPEUTIC EXERCISE CLASSES OR A SELF-CARE BOOK. MEASUREMENTS: PRIMARY OUTCOMES WERE BACK-RELATED FUNCTIONAL STATUS (MODIFIED 24-POINT ROLAND DISABILITY SCALE) AND "BOTHERSOMENESS" OF PAIN (11-POINT NUMERICAL SCALE). THE PRIMARY TIME POINT WAS 12 WEEKS. CLINICALLY SIGNIFICANT CHANGE WAS CONSIDERED TO BE 2.5 POINTS ON THE FUNCTIONAL STATUS SCALE AND 1.5 POINTS ON THE BOTHERSOMENESS SCALE. SECONDARY OUTCOMES WERE DAYS OF RESTRICTED ACTIVITY, GENERAL HEALTH STATUS, AND MEDICATION USE. RESULTS: AFTER ADJUSTMENT FOR BASELINE VALUES, BACK-RELATED FUNCTION IN THE YOGA GROUP WAS SUPERIOR TO THE BOOK AND EXERCISE GROUPS AT 12 WEEKS (YOGA VS. BOOK: MEAN DIFFERENCE, -3.4 [95% CI, -5.1 TO - 1.6] [P < 0.001]; YOGA VS. EXERCISE: MEAN DIFFERENCE, -1.8 [CI, -3.5 TO - 0.1] [P = 0.034]). NO SIGNIFICANT DIFFERENCES IN SYMPTOM BOTHERSOMENESS WERE FOUND BETWEEN ANY 2 GROUPS AT 12 WEEKS; AT 26 WEEKS, THE YOGA GROUP WAS SUPERIOR TO THE BOOK GROUP WITH RESPECT TO THIS MEASURE (MEAN DIFFERENCE, -2.2 [CI, -3.2 TO - 1.2]; P < 0.001). AT 26 WEEKS, BACK-RELATED FUNCTION IN THE YOGA GROUP WAS SUPERIOR TO THE BOOK GROUP (MEAN DIFFERENCE, -3.6 [CI, -5.4 TO - 1.8]; P < 0.001). LIMITATIONS: PARTICIPANTS IN THIS STUDY WERE FOLLOWED FOR ONLY 26 WEEKS AFTER RANDOMIZATION. ONLY 1 INSTRUCTOR DELIVERED EACH INTERVENTION. CONCLUSIONS: YOGA WAS MORE EFFECTIVE THAN A SELF-CARE BOOK FOR IMPROVING FUNCTION AND REDUCING CHRONIC LOW BACK PAIN, AND THE BENEFITS PERSISTED FOR AT LEAST SEVERAL MONTHS.	2005	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                             
7 2857  44 YOGA-BASED CARDIAC REHABILITATION AFTER ACUTE MYOCARDIAL INFARCTION: A RANDOMIZED TRIAL. BACKGROUND: GIVEN THE SHORTAGE OF CARDIAC REHABILITATION (CR) PROGRAMS IN INDIA AND POOR UPTAKE WORLDWIDE, THERE IS AN URGENT NEED TO FIND ALTERNATIVE MODELS OF CR THAT ARE INEXPENSIVE AND MAY OFFER CHOICE TO SUBGROUPS WITH POOR UPTAKE (E.G., WOMEN AND ELDERLY). OBJECTIVES: THIS STUDY SOUGHT TO EVALUATE THE EFFECTS OF YOGA-BASED CR (YOGA-CARE) ON MAJOR CARDIOVASCULAR EVENTS AND SELF-RATED HEALTH IN A MULTICENTER RANDOMIZED CONTROLLED TRIAL. METHODS: THE TRIAL WAS CONDUCTED IN 24 MEDICAL CENTERS ACROSS INDIA. THIS STUDY RECRUITED 3,959 PATIENTS WITH ACUTE MYOCARDIAL INFARCTION WITH A MEDIAN AND MINIMUM FOLLOW-UP OF 22 AND 6 MONTHS. PATIENTS WERE INDIVIDUALLY RANDOMIZED TO RECEIVE EITHER A YOGA-CARE PROGRAM (N = 1,970) OR ENHANCED STANDARD CARE INVOLVING EDUCATIONAL ADVICE (N = 1,989). THE CO-PRIMARY OUTCOMES WERE: 1) FIRST OCCURRENCE OF MAJOR ADVERSE CARDIOVASCULAR EVENTS (MACE) (COMPOSITE OF ALL-CAUSE MORTALITY, MYOCARDIAL INFARCTION, STROKE, OR EMERGENCY CARDIOVASCULAR HOSPITALIZATION); AND 2) SELF-RATED HEALTH ON THE EUROPEAN QUALITY OF LIFE-5 DIMENSIONS-5 LEVEL VISUAL ANALOGUE SCALE AT 12 WEEKS. RESULTS: MACE OCCURRED IN 131 (6.7%) PATIENTS IN THE YOGA-CARE GROUP AND 146 (7.4%) PATIENTS IN THE ENHANCED STANDARD CARE GROUP (HAZARD RATIO WITH YOGA-CARE: 0.90; 95% CONFIDENCE INTERVAL [CI]: 0.71 TO 1.15; P = 0.41). SELF-RATED HEALTH WAS 77 IN YOGA-CARE AND 75.7 IN THE ENHANCED STANDARD CARE GROUP (BASELINE-ADJUSTED MEAN DIFFERENCE IN FAVOR OF YOGA-CARE: 1.5; 95% CI: 0.5 TO 2.5; P = 0.002). THE YOGA-CARE GROUP HAD GREATER RETURN TO PRE-INFARCT ACTIVITIES, BUT THERE WAS NO DIFFERENCE IN TOBACCO CESSATION OR MEDICATION ADHERENCE BETWEEN THE TREATMENT GROUPS (SECONDARY OUTCOMES). CONCLUSIONS: YOGA-CARE IMPROVED SELF-RATED HEALTH AND RETURN TO PRE-INFARCT ACTIVITIES AFTER ACUTE MYOCARDIAL INFARCTION, BUT THE TRIAL LACKED STATISTICAL POWER TO SHOW A DIFFERENCE IN MACE. YOGA-CARE MAY BE AN OPTION WHEN CONVENTIONAL CR IS UNAVAILABLE OR UNACCEPTABLE TO INDIVIDUALS.

8 2831  60 YOGA VS. PHYSICAL THERAPY VS. EDUCATION FOR CHRONIC LOW BACK PAIN IN PREDOMINANTLY MINORITY POPULATIONS: STUDY PROTOCOL FOR A RANDOMIZED CONTROLLED TRIAL. BACKGROUND: CHRONIC LOW BACK PAIN CAUSES SUBSTANTIAL MORBIDITY AND COST TO SOCIETY WHILE DISPROPORTIONATELY IMPACTING LOW-INCOME AND MINORITY ADULTS. SEVERAL RANDOMIZED CONTROLLED TRIALS SHOW YOGA IS AN EFFECTIVE TREATMENT. HOWEVER, THE COMPARATIVE EFFECTIVENESS OF YOGA AND PHYSICAL THERAPY, A COMMON MAINSTREAM TREATMENT FOR CHRONIC LOW BACK PAIN, IS UNKNOWN. METHODS/DESIGN: THIS IS A RANDOMIZED CONTROLLED TRIAL FOR 320 PREDOMINANTLY LOW-INCOME MINORITY ADULTS WITH CHRONIC LOW BACK PAIN, COMPARING YOGA, PHYSICAL THERAPY, AND EDUCATION. INCLUSION CRITERIA ARE ADULTS 18-64 YEARS OLD WITH NON-SPECIFIC LOW BACK PAIN LASTING >/= 12 WEEKS AND A SELF-REPORTED AVERAGE PAIN INTENSITY OF >/= 4 ON A 0-10 SCALE. RECRUITMENT TAKES PLACE AT BOSTON MEDICAL CENTER, AN URBAN ACADEMIC SAFETY-NET HOSPITAL AND SEVEN FEDERALLY QUALIFIED COMMUNITY HEALTH CENTERS LOCATED IN DIVERSE NEIGHBORHOODS. THE 52-WEEK STUDY HAS AN INITIAL 12-WEEK TREATMENT PHASE WHERE PARTICIPANTS ARE RANDOMIZED IN A 2:2:1 RATIO INTO I) A STANDARDIZED WEEKLY HATHA YOGA CLASS SUPPLEMENTED BY HOME PRACTICE; II) A STANDARDIZED EVIDENCE-BASED EXERCISE THERAPY PROTOCOL ADAPTED FROM THE TREATMENT BASED CLASSIFICATION METHOD, INDIVIDUALLY DELIVERED BY A PHYSICAL THERAPIST AND SUPPLEMENTED BY HOME PRACTICE; AND III) EDUCATION DELIVERED THROUGH A SELF-CARE BOOK. CO-PRIMARY OUTCOME MEASURES ARE 12-WEEK PAIN INTENSITY MEASURED ON AN 11-POINT NUMERICAL RATING SCALE AND BACK-SPECIFIC FUNCTION MEASURED USING THE MODIFIED ROLAND MORRIS DISABILITY QUESTIONNAIRE. IN THE SUBSEQUENT 40-WEEK MAINTENANCE PHASE, YOGA PARTICIPANTS ARE RE-RANDOMIZED IN A 1:1 RATIO TO EITHER STRUCTURED MAINTENANCE YOGA CLASSES OR HOME PRACTICE ONLY. PHYSICAL THERAPY PARTICIPANTS ARE SIMILARLY RE-RANDOMIZED TO EITHER FIVE BOOSTER SESSIONS OR HOME PRACTICE ONLY. EDUCATION PARTICIPANTS CONTINUE TO FOLLOW RECOMMENDATIONS OF EDUCATIONAL MATERIALS. WE WILL ALSO ASSESS COST EFFECTIVENESS FROM THE PERSPECTIVES OF THE INDIVIDUAL, INSURERS, AND SOCIETY USING CLAIMS DATABASES, ELECTRONIC MEDICAL RECORDS, SELF-REPORT COST DATA, AND STUDY RECORDS. QUALITATIVE DATA FROM INTERVIEWS WILL ADD SUBJECTIVE DETAIL TO COMPLEMENT QUANTITATIVE DATA.

9  312  44 AN EXPLORATORY RANDOMIZED CONTROLLED TRIAL OF A 12-WEEK YOGA VERSUS EDUCATIONAL FILM PROGRAM FOR THE MANAGEMENT OF RESTLESS LEGS SYNDROME: FEASIBILITY AND ACCEPTABILITY. OBJECTIVES: THE PRIMARY OBJECTIVES OF THIS PILOT TRIAL WERE TO ASSESS THE STUDY FEASIBILITY AND ACCEPTABILITY OF THE 12-WEEK YOGA AND EDUCATIONAL FILM PROGRAMS FOR THE MANAGEMENT OF RESTLESS LEGS SYNDROME (RLS) IN PREPARATION FOR A FUTURE RANDOMIZED CONTROLLED TRIAL (RCT). MATERIALS AND METHODS: THIS PILOT, PARALLEL-ARM, RANDOMIZED FEASIBILITY TRIAL WAS CONDUCTED AT TWO SITES, MORGANTOWN, WV AND COLUMBUS, OH. YOGA GROUP PARTICIPANTS ATTENDED 75-MIN IYENGAR YOGA CLASSES, TWICE WEEKLY FOR 4 WEEKS, THEN ONCE A WEEK FOR 8 WEEKS (16 TOTAL CLASSES), AND COMPLETED A 30-MIN HOMEWORK ROUTINE ON NONCLASS DAYS. EDUCATIONAL FILM GROUP PARTICIPANTS ATTENDED ONCE WEEKLY, 75-MIN CLASSES (12 TOTAL CLASSES), WHICH INCLUDED INFORMATION ON RLS AND OTHER SLEEP DISORDERS, RLS MANAGEMENT INCLUDING SLEEP HYGIENE PRACTICES, AND COMPLEMENTARY THERAPIES. FEASIBILITY AND ACCEPTABILITY OUTCOMES INCLUDED PROGRAM SATISFACTION AND RECRUITMENT, RETENTION, AND ADHERENCE RATES. IN ADDITION, PARTICIPANTS WERE ASKED THEIR PREFERENCES REGARDING THREE YOGA CLASS SCHEDULE SCENARIOS FOR A FUTURE STUDY. ATTENDANCE, YOGA, AND TREATMENT LOGS WERE COLLECTED WEEKLY. PROGRAM EVALUATION AND YOGA SCHEDULING QUESTIONNAIRES WERE COLLECTED AT WEEK 12. RESULTS: FORTY-ONE ADULTS WITH MODERATE TO SEVERE RLS WERE RANDOMIZED TO A 12-WEEK YOGA (N = 19) OR EDUCATIONAL FILM (N = 22) PROGRAM. THIRTY PARTICIPANTS (73%) COMPLETED THE PROGRAM. YOGA AND EDUCATION GROUP PARTICIPANTS ATTENDED AN AVERAGE OF 13.0 +/- 0.84 (81%) AND 10.3 +/- 0.3 CLASSES (85%), RESPECTIVELY. PARTICIPANTS FROM BOTH GROUPS INDICATED SATISFACTION WITH THE STUDY. ALL YOGA GROUP RESPONDENTS TO THE PROGRAM EVALUATION REPORTED THEY WOULD LIKELY (N = 6) OR VERY LIKELY (N = 7) CONTINUE YOGA PRACTICE; 86.7% OF EDUCATION GROUP RESPONDENTS (13 OF 15) INDICATED THAT THEY WERE LIKELY (N = 7) OR VERY LIKELY (N = 6) TO MAKE LASTING CHANGES BASED ON WHAT THEY HAD LEARNED. THE PREFERRED SCHEDULE FOR A FUTURE STUDY WAS A 16-WEEK STUDY WITH ONCE-WEEKLY YOGA CLASSES. CONCLUSIONS: THE FINDINGS OF THIS STUDY SUGGEST THAT A LARGER RCT COMPARING YOGA WITH AN EDUCATIONAL FILM GROUP FOR THE MANAGEMENT OF RLS IS FEASIBLE.

10  193  56 A RANDOMIZED TRIAL COMPARING YOGA, STRETCHING, AND A SELF-CARE BOOK FOR CHRONIC LOW BACK PAIN. BACKGROUND: CHRONIC LOW BACK PAIN IS A COMMON PROBLEM LACKING HIGHLY EFFECTIVE TREATMENT OPTIONS. SMALL TRIALS SUGGEST THAT YOGA MAY HAVE BENEFITS FOR THIS CONDITION. THIS TRIAL WAS DESIGNED TO DETERMINE WHETHER YOGA IS MORE EFFECTIVE THAN CONVENTIONAL STRETCHING EXERCISES OR A SELF-CARE BOOK FOR PRIMARY CARE PATIENTS WITH CHRONIC LOW BACK PAIN. METHODS: A TOTAL OF 228 ADULTS WITH CHRONIC LOW BACK PAIN WERE RANDOMIZED TO 12 WEEKLY CLASSES OF YOGA (92 PATIENTS) OR CONVENTIONAL STRETCHING EXERCISES (91 PATIENTS) OR A SELF-CARE BOOK (45 PATIENTS). BACK-RELATED FUNCTIONAL STATUS (MODIFIED ROLAND DISABILITY QUESTIONNAIRE, A 23-POINT SCALE) AND BOTHERSOMENESS OF PAIN (AN 11-POINT NUMERICAL SCALE) AT 12 WEEKS WERE THE PRIMARY OUTCOMES. OUTCOMES WERE ASSESSED AT BASELINE, 6, 12, AND 26 WEEKS BY INTERVIEWERS UNAWARE OF TREATMENT GROUP. RESULTS: AFTER ADJUSTMENT FOR BASELINE VALUES, 12-WEEK OUTCOMES FOR THE YOGA GROUP WERE SUPERIOR TO THOSE FOR THE SELF-CARE GROUP (MEAN DIFFERENCE FOR FUNCTION, -2.5 [95% CI, -3.7 TO -1.3]; P < .001; MEAN DIFFERENCE FOR SYMPTOMS, -1.1 [95% CI, -1.7 TO -0.4]; P < .001). AT 26 WEEKS, FUNCTION FOR THE YOGA GROUP REMAINED SUPERIOR (MEAN DIFFERENCE, -1.8 [95% CI, -3.1 TO -0.5]; P < .001). YOGA WAS NOT SUPERIOR TO CONVENTIONAL STRETCHING EXERCISES AT ANY TIME POINT. CONCLUSION: YOGA CLASSES WERE MORE EFFECTIVE THAN A SELF-CARE BOOK, BUT NOT MORE EFFECTIVE THAN STRETCHING CLASSES, IN IMPROVING FUNCTION AND REDUCING SYMPTOMS DUE TO CHRONIC LOW BACK PAIN, WITH BENEFITS LASTING AT LEAST SEVERAL MONTHS.

11  162  49 A RANDOMISED CONTROLLED TRIAL OF YOGA FOR THE TREATMENT OF CHRONIC LOW BACK PAIN: RESULTS OF A PILOT STUDY. OBJECTIVE: TO CONDUCT A PILOT TRIAL OF YOGA FOR THE TREATMENT OF CHRONIC LOW BACK PAIN (LBP) TO INFORM THE FEASIBILITY AND PRACTICALITY OF CONDUCTING A FULL-SCALE TRIAL IN THE UK; AND TO ASSESS THE EFFICACY OF YOGA FOR THE TREATMENT OF CHRONIC LOW BACK PAIN. DESIGN: A PRAGMATIC RANDOMISED CONTROLLED TRIAL WAS UNDERTAKEN COMPARING YOGA TO USUAL CARE. PARTICIPANTS: TWENTY PARTICIPANTS WHO HAD PRESENTED TO THEIR GP WITH CHRONIC LOW BACK PAIN IN THE PREVIOUS 18 MONTHS WERE RECRUITED VIA GP RECORDS FROM ONE PRACTICE IN YORK, UK. INTERVENTIONS: TWENTY PATIENTS WERE RANDOMISED TO EITHER 12 WEEKLY 75-MIN SESSIONS OF SPECIALISED YOGA PLUS WRITTEN ADVICE, OR USUAL CARE PLUS WRITTEN ADVICE. ALLOCATION WAS 50/50. MAIN OUTCOME MEASURES: RECRUITMENT RATE, LEVELS OF INTERVENTION ATTENDANCE, AND LOSS TO FOLLOW-UP WERE THE MAIN NON-CLINICAL OUTCOMES. CHANGE AS MEASURED BY THE ROLAND AND MORRIS DISABILITY QUESTIONNAIRE WAS THE PRIMARY CLINICAL OUTCOME. CHANGES IN THE ABERDEEN BACK PAIN SCALE, SF-12, EQ-5D, AND PAIN SELF-EFFICACY WERE SECONDARY CLINICAL OUTCOMES. DATA WERE COLLECTED VIA POSTAL QUESTIONNAIRE AT BASELINE, 4 WEEKS, AND 12 WEEKS FOLLOW-UP. RESULTS: OF THE 286 PATIENTS IDENTIFIED FROM THE GP DATABASE, 52 (18%) CONSENTED AND RETURNED THE ELIGIBILITY QUESTIONNAIRE, OUT OF THESE 20 (6.9%) WERE ELIGIBLE AND RANDOMISED. THE TOTAL PERCENTAGE OF PATIENTS RANDOMISED FROM THE GP PRACTICE POPULATION WAS 0.28%. TEN PATIENTS WERE RANDOMISED TO YOGA, RECEIVING AN AVERAGE OF 1.7 SESSIONS (RANGE 0-5), AND 10 WERE RANDOMISED TO USUAL CARE. AT 12 WEEKS FOLLOW-UP DATA WAS RECEIVED FROM 60% OF PATIENTS IN THE YOGA GROUP AND 90% OF PATIENTS IN THE USUAL CARE GROUP (75% OVERALL). NO SIGNIFICANT DIFFERENCES WERE SEEN BETWEEN GROUPS IN CLINICAL OUTCOMES APART FROM ON THE ABERDEEN BACK PAIN SCALE AT FOUR WEEKS FOLLOW-UP WHERE THE YOGA GROUP REPORTED SIGNIFICANTLY LESS PAIN. CONCLUSION: THIS PILOT STUDY PROVIDED USEFUL DATA AND INFORMATION TO INFORM THE DESIGN AND DEVELOPMENT OF A FULL-SCALE TRIAL OF YOGA FOR CLBP IN THE UK. A KEY FINDING IS THE CALCULATION OF GP PRACTICE TOTAL LIST SIZE REQUIRED FOR PATIENT RECRUITMENT IN A FULL-SCALE TRIAL, AND THE NEED TO IMPLEMENT METHODS TO INCREASE CLASS ATTENDANCE.	2010	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                   
12  507  46 COMPARATIVE EFFECTIVENESS OF PILATES AND YOGA GROUP EXERCISE INTERVENTIONS FOR CHRONIC MECHANICAL NECK PAIN: QUASI-RANDOMISED PARALLEL CONTROLLED STUDY. OBJECTIVES: TO DETERMINE THE EFFECTIVENESS OF PILATES AND YOGA GROUP EXERCISE INTERVENTIONS FOR INDIVIDUALS WITH CHRONIC NECK PAIN (CNP). DESIGN: QUASI-RANDOMISED PARALLEL CONTROLLED STUDY. SETTING: COMMUNITY, UNIVERSITY AND PRIVATE PRACTICE SETTINGS IN FOUR LOCATIONS. PARTICIPANTS: FIFTY-SIX INDIVIDUALS WITH CNP SCORING >/=3/10 ON THE NUMERIC PAIN RATING SCALE FOR >3 MONTHS (CONTROLS N=17, PILATES N=20, YOGA N=19). INTERVENTIONS: EXERCISE PARTICIPANTS COMPLETED 12 SMALL-GROUP SESSIONS WITH MODIFICATIONS AND PROGRESSIONS SUPERVISED BY A PHYSIOTHERAPIST. MAIN OUTCOME MEASURES: THE PRIMARY OUTCOME MEASURE WAS THE NECK DISABILITY INDEX (NDI). SECONDARY OUTCOMES WERE PAIN RATINGS, RANGE OF MOVEMENT AND POSTURAL MEASUREMENTS COLLECTED AT BASELINE, 6 WEEKS AND 12 WEEKS. FOLLOW-UP WAS PERFORMED 6 WEEKS AFTER COMPLETION OF THE EXERCISE CLASSES (WEEK 18). RESULTS: NDI DECREASED SIGNIFICANTLY IN THE PILATES {BASELINE: 11.1 [STANDARD DEVIATION (SD) 4.3] VS WEEK 12: 6.8 (SD 4.3); MEAN DIFFERENCE -4.3 (95% CONFIDENCE INTERVAL -1.64 TO -6.7); P<0.001} AND YOGA GROUPS [BASELINE: 12.8 (SD 7.4) VS WEEK 12: 8.1 (SD 5.6); MEAN DIFFERENCE -4.7 (95% CONFIDENCE INTERVAL -2.1 TO -7.4); P<0.00], WITH NO CHANGE IN THE CONTROL GROUP. PAIN RATINGS ALSO IMPROVED SIGNIFICANTLY. MODERATE-TO-LARGE EFFECT SIZES (0.7 TO 1.8) AND LOW NUMBERS NEEDED TO TREAT WERE FOUND. THERE WERE NO DIFFERENCES IN OUTCOMES BETWEEN THE EXERCISE GROUPS OR ASSOCIATED ADVERSE EFFECTS. NO IMPROVEMENTS IN RANGE OF MOVEMENT OR POSTURE WERE FOUND. CONCLUSIONS: PILATES AND YOGA GROUP EXERCISE INTERVENTIONS WITH APPROPRIATE MODIFICATIONS AND SUPERVISION WERE SAFE AND EQUALLY EFFECTIVE FOR DECREASING DISABILITY AND PAIN COMPARED WITH THE CONTROL GROUP FOR INDIVIDUALS WITH MILD-TO-MODERATE CNP. PHYSIOTHERAPISTS MAY CONSIDER INCLUDING THESE APPROACHES IN A PLAN OF CARE.

13 2851  52 YOGA, PHYSICAL THERAPY, AND BACK PAIN EDUCATION FOR SLEEP QUALITY IN LOW-INCOME RACIALLY DIVERSE ADULTS WITH CHRONIC LOW BACK PAIN: A SECONDARY ANALYSIS OF A RANDOMIZED CONTROLLED TRIAL. BACKGROUND: POOR SLEEP IS COMMON AMONG ADULTS WITH CHRONIC LOW BACK PAIN (CLBP), BUT THE INFLUENCE OF CLBP TREATMENTS, SUCH AS YOGA AND PHYSICAL THERAPY (PT), ON SLEEP QUALITY IS UNDER STUDIED. OBJECTIVE: EVALUATE THE EFFECTIVENESS OF YOGA AND PT FOR IMPROVING SLEEP QUALITY IN ADULTS WITH CLBP. DESIGN: SECONDARY ANALYSIS OF A RANDOMIZED CONTROLLED TRIAL. SETTING: ACADEMIC SAFETY-NET HOSPITAL AND 7 AFFILIATED COMMUNITY HEALTH CENTERS. PARTICIPANTS: A TOTAL OF 320 ADULTS WITH CLBP. INTERVENTION: TWELVE WEEKLY YOGA CLASSES, 1-ON-1 PT SESSIONS, OR AN EDUCATIONAL BOOK. MAIN MEASURES: SLEEP QUALITY WAS MEASURED USING THE PITTSBURGH SLEEP QUALITY INDEX (PSQI) GLOBAL SCORE (0-21) AT BASELINE, 12 WEEKS, AND 52 WEEKS. ADDITIONALLY, WE ALSO EVALUATED HOW THE PROPORTION OF PARTICIPANTS WHO ACHIEVED A CLINICALLY MEANINGFUL IMPROVEMENT IN SLEEP QUALITY (> 3-POINT REDUCTION IN PSQI) AT 12 WEEKS VARIED BY CHANGES IN PAIN AND PHYSICAL FUNCTION AT 6 WEEKS. KEY RESULTS: AMONG PARTICIPANTS (MEAN AGE = 46.0, 64% FEMALE, 82% NON-WHITE), NEARLY ALL (92%) REPORTED POOR SLEEP QUALITY (PSQI > 5) AT BASELINE. AT 12 WEEKS, MODEST IMPROVEMENTS IN SLEEP QUALITY WERE OBSERVED AMONG THE YOGA (PSQI MEAN DIFFERENCE [MD] = - 1.19, 95% CONFIDENCE INTERVAL [CI] - 1.82, - 0.55) AND PT (PSQI MD = - 0.91, 95% CI - 1.61, - 0.20) GROUPS. PARTICIPANTS WHO REPORTED A >/= 30% IMPROVEMENT IN PAIN OR PHYSICAL FUNCTION AT 6 WEEKS, COMPARED WITH THOSE WHO IMPROVED < 10%, WERE MORE LIKELY TO BE A SLEEP QUALITY RESPONDER AT 12 WEEKS (ODDS RATIO [OR] = 3.51, 95% CI 1.73, 7.11 AND OR = 2.16, 95% CI 1.18, 3.95, RESPECTIVELY). RESULTS WERE SIMILAR AT 52 WEEKS. CONCLUSION: IN A SAMPLE OF ADULTS WITH CLBP, VIRTUALLY ALL WITH POOR SLEEP QUALITY PRIOR TO INTERVENTION, MODEST BUT STATISTICALLY SIGNIFICANT IMPROVEMENTS IN SLEEP QUALITY WERE OBSERVED WITH BOTH YOGA AND PT. IRRESPECTIVE OF TREATMENT, CLINICALLY IMPORTANT SLEEP IMPROVEMENTS AT THE END OF THE INTERVENTION WERE ASSOCIATED WITH MID-INTERVENTION PAIN AND PHYSICAL FUNCTION IMPROVEMENTS.

14  900  32 EFFECTIVENESS AND COST-EFFECTIVENESS OF A YOGA-BASED CARDIAC REHABILITATION (YOGA-CARE) PROGRAM FOLLOWING ACUTE MYOCARDIAL INFARCTION: STUDY RATIONALE AND DESIGN OF A MULTI-CENTER RANDOMIZED CONTROLLED TRIAL. BACKGROUND: CARDIAC REHABILITATION (CR) IS A STANDARD TREATMENT FOR SECONDARY PREVENTION OF ACUTE MYOCARDIAL INFARCTION (AMI) IN HIGH INCOME COUNTRIES (HICS), BUT IT IS INACCESSIBLE TO MOST PATIENTS IN INDIA DUE TO HIGH COSTS AND SKILLS REQUIRED FOR MULTIDISCIPLINARY CR TEAMS. WE DEVELOPED A LOW-COST AND SCALABLE CR PROGRAM BASED ON CULTURALLY-ACCEPTABLE PRACTICE OF YOGA (YOGA-CARE). IN THIS PAPER, WE REPORT THE RATIONALE AND DESIGN FOR EVALUATION OF ITS EFFECTIVENESS AND COST-EFFECTIVENESS. METHODS: THIS IS A MULTI-CENTER, SINGLE-BLIND, TWO-ARM PARALLEL-GROUP RANDOMIZED CONTROLLED TRIAL ACROSS 22 CARDIAC CARE HOSPITALS IN INDIA. FOUR THOUSAND PATIENTS AGED 18-80YEARS WITH AMI WILL BE RECRUITED AND RANDOMIZED 1:1 TO RECEIVE YOGA-CARE PROGRAM (13 SESSIONS SUPERVISED BY AN INSTRUCTOR AND ENCOURAGEMENT TO SELF-PRACTICE DAILY) OR ENHANCED STANDARD CARE (3 SESSIONS OF HEALTH EDUCATION) DELIVERED OVER A PERIOD OF THREE MONTHS. PARTICIPANTS WILL BE FOLLOWED 3-MONTHLY TILL THE END OF THE TRIAL. THE CO-PRIMARY OUTCOMES ARE A) TIME TO OCCURRENCE OF FIRST CARDIOVASCULAR EVENT (COMPOSITE OF ALL-CAUSE MORTALITY, NON-FATAL MYOCARDIAL INFARCTION, NON-FATAL STROKE AND EMERGENCY CARDIOVASCULAR HOSPITALIZATION), AND B) QUALITY OF LIFE (EURO-QOL-5L) AT 12WEEKS. SECONDARY OUTCOMES INCLUDE NEED FOR REVASCULARIZATION PROCEDURES, RETURN TO PRE-INFARCT ACTIVITIES, TOBACCO CESSATION, MEDICATION ADHERENCE, AND COST-EFFECTIVENESS OF THE INTERVENTION. CONCLUSION: THIS TRIAL WILL ALONE CONTRIBUTE >20% PARTICIPANTS TO EXISTING META-ANALYSES OF RANDOMIZED TRIALS OF CR WORLDWIDE. IF YOGA-CARE IS FOUND TO BE EFFECTIVE, IT HAS THE POTENTIAL TO SAVE MILLIONS OF LIVES AND TRANSFORM CARE OF AMI PATIENTS IN INDIA AND OTHER LOW AND MIDDLE INCOME COUNTRY SETTINGS.	2019	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                        
15  945  48 EFFECTS OF A 12-WEEK YOGA VERSUS A 12-WEEK EDUCATIONAL FILM INTERVENTION ON SYMPTOMS OF RESTLESS LEGS SYNDROME AND RELATED OUTCOMES: AN EXPLORATORY RANDOMIZED CONTROLLED TRIAL. STUDY OBJECTIVES: TO ASSESS THE EFFECTS OF A YOGA VERSUS EDUCATIONAL FILM (EF) PROGRAM ON RESTLESS LEGS SYNDROME (RLS) SYMPTOMS AND RELATED OUTCOMES IN ADULTS WITH RLS. METHODS: FORTY-ONE COMMUNITY-DWELLING, AMBULATORY NONPREGNANT ADULTS WITH MODERATE TO SEVERE RLS WERE RANDOMIZED TO A 12-WEEK YOGA (N = 19) OR EF PROGRAM (N = 22). IN ADDITION TO ATTENDING CLASSES, ALL PARTICIPANTS COMPLETED PRACTICE/TREATMENT LOGS. YOGA GROUP PARTICIPANTS WERE ASKED TO PRACTICE AT HOME 30 MINUTES PER DAY ON NONCLASS DAYS; EF PARTICIPANTS WERE INSTRUCTED TO RECORD ANY RLS TREATMENTS USED ON THEIR DAILY LOGS. CORE OUTCOMES ASSESSED PRETREATMENT AND POSTTREATMENT WERE RLS SYMPTOMS AND SYMPTOM SEVERITY (INTERNATIONAL RLS STUDY GROUP SCALE (IRLS) AND RLS ORDINAL SCALE), SLEEP QUALITY, MOOD, PERCEIVED STRESS, AND QUALITY OF LIFE (QOL). RESULTS: THIRTY ADULTS (13 YOGA, 17 EF), AGED 24 TO 73 (MEAN = 50.4 +/- 2.4 YEARS), COMPLETED THE 12-WEEK STUDY (78% FEMALE, 80.5% WHITE). POST-INTERVENTION, BOTH GROUPS SHOWED SIGNIFICANT IMPROVEMENT IN RLS SYMPTOMS AND SEVERITY, PERCEIVED STRESS, MOOD, AND QOL-MENTAL HEALTH (P </= .04). RELATIVE TO THE EF GROUP, YOGA PARTICIPANTS DEMONSTRATED SIGNIFICANTLY GREATER REDUCTIONS IN RLS SYMPTOMS AND SYMPTOM SEVERITY (P </= .01), AND GREATER IMPROVEMENTS IN PERCEIVED STRESS AND MOOD (P </= .04), AS WELL AS SLEEP QUALITY (P = .09); RLS SYMPTOMS DECREASED TO MINIMAL/MILD IN 77% OF YOGA GROUP PARTICIPANTS, WITH NONE SCORING IN THE SEVERE RANGE BY WEEK 12, VERSUS 24% AND 12%, RESPECTIVELY, IN EF PARTICIPANTS. IN THE YOGA GROUP, IRLS AND RLS SEVERITY SCORES DECLINED WITH INCREASING MINUTES OF HOMEWORK PRACTICE (R = .7, P = .009 AND R = .6, P = .03, RESPECTIVELY), SUGGESTING A POSSIBLE DOSE-RESPONSE RELATIONSHIP. CONCLUSIONS: FINDINGS OF THIS EXPLORATORY RCT SUGGEST THAT YOGA MAY BE EFFECTIVE IN REDUCING RLS SYMPTOMS AND SYMPTOM SEVERITY, DECREASING PERCEIVED STRESS, AND IMPROVING MOOD AND SLEEP IN ADULTS WITH RLS.

16 2558  60 YOGA FOR CHRONIC LOW BACK PAIN IN A PREDOMINANTLY MINORITY POPULATION: A PILOT RANDOMIZED CONTROLLED TRIAL. BACKGROUND: SEVERAL STUDIES SUGGEST YOGA MAY BE EFFECTIVE FOR CHRONIC LOW BACK PAIN; HOWEVER, TRIALS TARGETING MINORITIES HAVE NOT BEEN CONDUCTED. PRIMARY STUDY OBJECTIVES: ASSESS THE FEASIBILITY OF STUDYING YOGA IN A PREDOMINANTLY MINORITY POPULATION WITH CHRONIC LOW BACK PAIN. COLLECT PRELIMINARY DATA TO PLAN A LARGER POWERED STUDY. STUDY DESIGN: PILOT RANDOMIZED CONTROLLED TRIAL. SETTING: TWO COMMUNITY HEALTH CENTERS IN A RACIALLY DIVERSE NEIGHBORHOOD OF BOSTON, MASSACHUSETTS. PARTICIPANTS: THIRTY ENGLISH-SPEAKING ADULTS (MEAN AGE 44 YEARS, 83% FEMALE, 83% RACIAL/ETHNIC MINORITIES; 48% WITH INCOMES < OR = $30,000) WITH MODERATE-TO-SEVERE CHRONIC LOW BACK PAIN. INTERVENTIONS: STANDARDIZED SERIES OF WEEKLY HATHA YOGA CLASSES FOR 12 WEEKS COMPARED TO A WAITLIST USUAL CARE CONTROL. OUTCOME MEASURES: FEASIBILITY MEASURED BY TIME TO COMPLETE ENROLLMENT, PROPORTION OF RACIAL/ETHNIC MINORITIES ENROLLED, RETENTION RATES, AND ADVERSE EVENTS. PRIMARY EFFICACY OUTCOMES WERE CHANGES FROM BASELINE TO 12 WEEKS IN PAIN SCORE (0=NO PAIN TO 10=WORST POSSIBLE PAIN) AND BACK-RELATED FUNCTION USING THE MODIFIED ROLAND-MORRIS DISABILITY QUESTIONNAIRE (0-23 POINT SCALE, HIGHER SCORES REFLECT POORER FUNCTION). SECONDARY EFFICACY OUTCOMES WERE ANALGESIC USE, GLOBAL IMPROVEMENT, AND QUALITY OF LIFE (SF-36). RESULTS: RECRUITMENT TOOK 2 MONTHS. RETENTION RATES WERE 97% AT 12 WEEKS AND 77% AT 26 WEEKS. MEAN PAIN SCORES FOR YOGA DECREASED FROM BASELINE TO 12 WEEKS (6.7 TO 4.4) COMPARED TO USUAL CARE, WHICH DECREASED FROM 7.5 TO 7.1 (P=.02). MEAN ROLAND SCORES FOR YOGA DECREASED FROM 14.5 TO 8.2 COMPARED TO USUAL CARE, WHICH DECREASED FROM 16.1 TO 12.5 (P=.28). AT 12 WEEKS, YOGA COMPARED TO USUAL CARE PARTICIPANTS REPORTED LESS ANALGESIC USE (13% VS 73%, P=.003), LESS OPIATE USE (0% VS 33%, P=.04), AND GREATER OVERALL IMPROVEMENT (73% VS 27%, P=.03). THERE WERE NO DIFFERENCES IN SF-36 SCORES AND NO SERIOUS ADVERSE EVENTS. CONCLUSION: A YOGA STUDY INTERVENTION IN A PREDOMINANTLY MINORITY POPULATION WITH CHRONIC LOW BACK PAIN WAS MODERATELY FEASIBLE AND MAY BE MORE EFFECTIVE THAN USUAL CARE FOR REDUCING PAIN AND PAIN MEDICATION USE.	2009	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                           
17 2596  56 YOGA FOR MILITARY VETERANS WITH CHRONIC LOW BACK PAIN: A RANDOMIZED CLINICAL TRIAL. INTRODUCTION: CHRONIC LOW BACK PAIN (CLBP) IS PREVALENT, ESPECIALLY AMONG MILITARY VETERANS. MANY CLBP TREATMENT OPTIONS HAVE LIMITED BENEFITS AND ARE ACCOMPANIED BY SIDE EFFECTS. MAJOR EFFORTS TO REDUCE OPIOID USE AND EMBRACE NONPHARMACOLOGICAL PAIN TREATMENTS HAVE RESULTED. RESEARCH WITH COMMUNITY CLBP PATIENTS INDICATES THAT YOGA CAN IMPROVE HEALTH OUTCOMES AND HAS FEW SIDE EFFECTS. THE BENEFITS OF YOGA AMONG MILITARY VETERANS WERE EXAMINED. DESIGN: PARTICIPANTS WERE RANDOMIZED TO EITHER YOGA OR DELAYED YOGA TREATMENT IN 2013-2015. OUTCOMES WERE ASSESSED AT BASELINE, 6 WEEKS, 12 WEEKS, AND 6 MONTHS. INTENTION-TO-TREAT ANALYSES OCCURRED IN 2016. SETTING/PARTICIPANTS: ONE HUNDRED AND FIFTY MILITARY VETERANS WITH CLBP WERE RECRUITED FROM A MAJOR VETERANS AFFAIRS MEDICAL CENTER IN CALIFORNIA. INTERVENTION: YOGA CLASSES (WITH HOME PRACTICE) WERE LED BY A CERTIFIED INSTRUCTOR TWICE WEEKLY FOR 12 WEEKS, AND CONSISTED PRIMARILY OF PHYSICAL POSTURES, MOVEMENT, AND BREATHING TECHNIQUES. MAIN OUTCOME MEASURES: THE PRIMARY OUTCOME WAS ROLAND-MORRIS DISABILITY QUESTIONNAIRE SCORES AFTER 12 WEEKS. PAIN INTENSITY WAS IDENTIFIED AS AN IMPORTANT SECONDARY OUTCOME. RESULTS: PARTICIPANT CHARACTERISTICS WERE MEAN AGE 53 YEARS, 26% WERE FEMALE, 35% WERE UNEMPLOYED OR DISABLED, AND MEAN BACK PAIN DURATION WAS 15 YEARS. IMPROVEMENTS IN ROLAND-MORRIS DISABILITY QUESTIONNAIRE SCORES DID NOT DIFFER BETWEEN THE TWO GROUPS AT 12 WEEKS, BUT YOGA PARTICIPANTS HAD GREATER REDUCTIONS IN ROLAND-MORRIS DISABILITY QUESTIONNAIRE SCORES THAN DELAYED TREATMENT PARTICIPANTS AT 6 MONTHS -2.48 (95% CI= -4.08, -0.87). YOGA PARTICIPANTS IMPROVED MORE ON PAIN INTENSITY AT 12 WEEKS AND AT 6 MONTHS. OPIOID MEDICATION USE DECLINED AMONG ALL PARTICIPANTS, BUT GROUP DIFFERENCES WERE NOT FOUND. CONCLUSIONS: YOGA IMPROVED HEALTH OUTCOMES AMONG VETERANS DESPITE EVIDENCE THEY HAD FEWER RESOURCES, WORSE HEALTH, AND MORE CHALLENGES ATTENDING YOGA SESSIONS THAN COMMUNITY SAMPLES STUDIED PREVIOUSLY. THE MAGNITUDE OF PAIN INTENSITY DECLINE WAS SMALL, BUT OCCURRED IN THE CONTEXT OF REDUCED OPIOID USE. THE FINDINGS SUPPORT WIDER IMPLEMENTATION OF YOGA PROGRAMS FOR VETERANS.

18 1563  24 LONGITUDINAL EFFECTS OF A COMBINED PROGRAM OF PELVIC FLOOR MUSCLE TRAINING AND YOGA ON GENITOURINARY SYMPTOMS IN ASIAN WOMEN OF OLDER AGE: A RANDOMIZED EXPERIMENTAL STUDY. THIS PARALLEL-TWO-GROUP RANDOMIZED EXPERIMENTAL STUDY INCLUDING A SUPERVISED GROUP AND AN UNSUPERVISED GROUP EXAMINED THE LONGITUDINAL EFFECTS OF PELVIC FLOOR MUSCLE TRAINING (PFMT) COMBINED WITH YOGA ON GENITOURINARY SYMPTOMS AND THE HEALTH-RELATED QUALITY OF LIFE (HRQOL), AND COMPARED PRACTICE ADHERENCE RATES OF THE TWO GROUPS. A SAMPLE OF WOMEN EXPERIENCING >/=1 GENITOURINARY SYMPTOM(S) WERE RECRUITED AND ASSIGNED TO A SUPERVISED GROUP OR AN UNSUPERVISED GROUP. THE SUPERVISED GROUP ATTENDED SUPERVISED GROUP PRACTICE SESSIONS AND PERFORMED AT-HOME PRACTICE OF PFMT AND YOGA. THE UNSUPERVISED GROUP PERFORMED AT-HOME PRACTICE OF PFMT AND YOGA. INFORMATION WAS COLLECTED AT FIVE TIME POINTS (N = 91). GENERALIZED ESTIMATING EQUATION PROCEDURES WERE USED TO EXAMINE THE INTERVENTION EFFECTS. AN INDEPENDENT T-TEST WAS CONDUCTED TO COMPARE THE PRACTICE ADHERENCE RATES. BOTH GROUPS' GENITOURINARY SYMPTOMS AND HRQOL SIGNIFICANTLY IMPROVED OVER TIME. THE SUPERVISED GROUP DISPLAYED GREATER IMPROVEMENTS IN GENITOURINARY SYMPTOMS AND HRQOL AND BETTER ADHERENCE THAN DID THE UNSUPERVISED GROUP.	2022	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                
19 1699  66 PARTICIPANT CHARACTERISTICS ASSOCIATED WITH SYMPTOMATIC IMPROVEMENT FROM YOGA FOR CHRONIC LOW BACK PAIN. CONTEXT: STUDIES SUGGEST THAT YOGA IS EFFECTIVE FOR MODERATE TO SEVERE CHRONIC LOW BACK PAIN (CLBP) IN DIVERSE PREDOMINANTLY LOWER SOCIOECONOMIC STATUS POPULATIONS. HOWEVER, LITTLE IS KNOWN ABOUT FACTORS ASSOCIATED WITH BENEFIT FROM THE YOGA INTERVENTION. OBJECTIVE: IDENTIFY FACTORS AT BASELINE INDEPENDENTLY ASSOCIATED WITH GREATER EFFICACY AMONG PARTICIPANTS IN A STUDY OF YOGA FOR CLBP. DESIGN: FROM SEPTEMBER-DECEMBER 2011, A 12-WEEK RANDOMIZED DOSING TRIAL WAS CONDUCTED COMPARING WEEKLY VS. TWICE-WEEKLY 75-MINUTE HATHA YOGA CLASSES FOR 95 PREDOMINANTLY LOW-INCOME MINORITY ADULTS WITH NONSPECIFIC CLBP. PARTICIPANT CHARACTERISTICS COLLECTED AT BASELINE WERE USED TO DETERMINE FACTORS BEYOND TREATMENT ASSIGNMENT (REPORTED IN THE INITIAL STUDY) THAT PREDICTED OUTCOME. WE USED BIVARIATE TESTING TO IDENTIFY BASELINE CHARACTERISTICS ASSOCIATED WITH IMPROVEMENT IN FUNCTION AND PAIN, AND INCLUDED SELECT FACTORS IN A MULTIVARIATE LINEAR REGRESSION. SETTING: RECRUITMENT AND CLASSES OCCURRED IN AN ACADEMIC SAFETY-NET HOSPITAL AND FIVE AFFILIATED COMMUNITY HEALTH CENTERS IN BOSTON, MASSACHUSETTS. PARTICIPANTS: NINETY-FIVE ADULTS WITH NONSPECIFIC CLBP, AGES RANGING FROM 20-64 (MEAN 48) YEARS; 72 WOMEN AND 23 MEN. OUTCOME MEASURES: PRIMARY OUTCOMES WERE CHANGES IN BACK-RELATED FUNCTION (MODIFIED ROLAND-MORRIS DISABILITY QUESTIONNAIRE, RMDQ; 0-23) AND MEAN LOW BACK PAIN INTENSITY (0-10) IN THE PREVIOUS WEEK, FROM BASELINE TO WEEK 12. RESULTS: ADJUSTING FOR GROUP ASSIGNMENT, BASELINE RMDQ, AGE, AND GENDER, FOREIGN NATIONALITY AND LOWER BASELINE SF36 PHYSICAL COMPONENT SCORE (PCS) WERE INDEPENDENTLY ASSOCIATED WITH IMPROVEMENT IN RMDQ. GREATER THAN HIGH SCHOOL EDUCATION LEVEL, CLBP LESS THAN 1 YEAR, AND LOWER BASELINE SF36 PCS WERE INDEPENDENTLY ASSOCIATED WITH IMPROVEMENT IN PAIN INTENSITY. OTHER DEMOGRAPHICS INCLUDING RACE, INCOME, GENDER, BMI, AND USE OF PAIN MEDICATIONS WERE NOT ASSOCIATED WITH EITHER OUTCOME. CONCLUSIONS: POOR PHYSICAL HEALTH AT BASELINE IS ASSOCIATED WITH GREATER IMPROVEMENT FROM YOGA IN BACK-RELATED FUNCTION AND PAIN. RACE, INCOME, AND BODY MASS INDEX DO NOT AFFECT THE POTENTIAL FOR A PERSON WITH LOW BACK PAIN TO EXPERIENCE BENEFIT FROM YOGA.	2014	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                               
20  540  46 COMPLIANCE EFFECTS IN A RANDOMISED CONTROLLED TRIAL OF YOGA FOR CHRONIC LOW BACK PAIN: A METHODOLOGICAL STUDY. STUDY DESIGN: METHODOLOGICAL STUDY NESTED WITHIN A MULTICENTRE RANDOMISED CONTROLLED TRIAL (RCT) OF YOGA PLUS USUAL GENERAL PRACTITIONER (GP) CARE VS USUAL GP CARE FOR CHRONIC LOW BACK PAIN. OBJECTIVE: TO EXPLORE THE TREATMENT EFFECTS OF NON-COMPLIANCE USING THREE APPROACHES IN AN RCT EVALUATING YOGA FOR LOW BACK PAIN. SUMMARY OF BACKGROUND DATA: A LARGE MULTICENTRE RCT USING INTENTION-TO-TREAT (ITT) ANALYSIS FOUND THAT PARTICIPANTS WITH CHRONIC LOW BACK PAIN WHO WERE OFFERED A 12-WEEK PROGRESSIVE PROGRAMME OF YOGA PLUS USUAL GP CARE HAD BETTER BACK FUNCTION THAN THOSE OFFERED USUAL GP CARE ALONE. HOWEVER, ITT ANALYSIS CAN UNDERESTIMATE THE EFFECT OF TREATMENT IN THOSE WHO COMPLY WITH TREATMENT. AS SUCH, THE DATA WERE ANALYSED USING OTHER APPROACHES TO ASSESS THE PROBLEM OF NON-COMPLIANCE. THE MAIN OUTCOME MEASURE WAS THE SELF-REPORTED ROLAND MORRIS DISABILITY QUESTIONNAIRE (RMDQ). METHODS: COMPLIER AVERAGE CAUSAL EFFECT (CACE) ANALYSIS, PER-PROTOCOL ANALYSIS AND ON-TREATMENT ANALYSIS WERE CONDUCTED ON THE DATA OF PARTICIPANTS WHO WERE FULLY COMPLIANT, PREDEFINED AS ATTENDANCE OF AT LEAST THREE OF THE FIRST SIX SESSIONS AND AT LEAST THREE OTHER SESSIONS. THE ANALYSIS WAS REPEATED FOR PARTICIPANTS WHO HAD ATTENDED AT LEAST ONE YOGA SESSION (I.E. ANY COMPLIANCE), WHICH INCLUDED PARTICIPANTS WHO WERE FULLY COMPLIANT. EACH APPROACH WAS DESCRIBED, INCLUDING STRENGTHS AND WEAKNESSES, AND THE RESULTS OF THE DIFFERENT APPROACHES WERE COMPARED WITH THOSE OF THE ITT ANALYSIS. RESULTS: FOR THE PARTICIPANTS WHO WERE FULLY COMPLIANT (N=93, 60%), A LARGER BENEFICIAL TREATMENT EFFECT WAS SEEN USING CACE ANALYSIS COMPARED WITH PER-PROTOCOL, ON-TREATMENT AND ITT ANALYSES AT 3 AND 12 MONTHS. THE DIFFERENCE IN MEAN CHANGE IN RMDQ SCORE BETWEEN RANDOMISED GROUPS WAS -3.30 [95% CONFIDENCE INTERVAL (CI) -4.90 TO -1.70, P<0.001] AT 3 MONTHS AND -2.23 (95% CI -3.93 TO -0.53, P=0.010) AT 12 MONTHS FOR CACE ANALYSIS, -3.12 (95% CI -4.26 TO -1.98, P<0.001) AT 3 MONTHS AND -2.11 (95% CI -3.33 TO -0.89, P=0.001) AT 12 MONTHS FOR PER-PROTOCOL ANALYSIS, AND -2.91 (95% CI -4.06 TO -1.76, P<0.001) AT 3 MONTHS AND -2.10 (95% CI -3.31 TO -0.89, P=0.001) AT 12 MONTHS FOR ON-TREATMENT ANALYSIS. FOR THE PARTICIPANTS WHO DEMONSTRATED ANY COMPLIANCE (N=133, 85%), THE RESULTS WERE GENERALLY CONSISTENT WITH THE FULLY COMPLIANT GROUP AT 3 MONTHS, BUT THE TREATMENT EFFECT WAS SMALLER. THE DIFFERENCE IN MEAN CHANGE IN RMDQ SCORE BETWEEN RANDOMISED GROUPS WAS -2.45 (95% CI -3.67 TO -1.24) FOR CACE ANALYSIS, -2.30 (95% CI -3.43 TO 1.17) FOR PER-PROTOCOL ANALYSIS AND -2.15 (95% CI -3.25 TO -1.06) FOR ON-TREATMENT ANALYSIS, WHICH WAS SLIGHTLY LESS THAN THAT FOR ITT ANALYSIS. IN CONTRAST, AT 12 MONTHS, PER-PROTOCOL AND ON-TREATMENT ANALYSES SHOWED A LARGER TREATMENT EFFECT COMPARED WITH CACE AND ITT ANALYSES: PER PROTOCOL ANALYSIS -1.86 (95% CI -3.02 TO -0.71), ON-TREATMENT ANALYSIS -1.99 (95% CI -3.13 TO -0.86) AND CACE ANALYSIS -1.67 (95% CI -2.95 TO -0.40). CONCLUSION: ITT ANALYSIS ESTIMATED A SLIGHTLY SMALLER TREATMENT EFFECT IN PARTICIPANTS WHO COMPLIED WITH TREATMENT. WHEN EXAMINING COMPLIANCE, CACE ANALYSIS IS MORE RIGOROUS THAN PER-PROTOCOL AND ON-TREATMENT ANALYSES. USING CACE ANALYSIS, THE TREATMENT EFFECT WAS LARGER IN PARTICIPANTS WHO COMPLIED WITH TREATMENT COMPARED WITH PARTICIPANTS WHO WERE ALLOCATED TO TREATMENT, AND THE DIFFERENCE BETWEEN ITT AND CACE ANALYSES FOR THE FULLY COMPLIANT GROUP AT 3 MONTHS WAS SMALL BUT CLINICALLY IMPORTANT. PER-PROTOCOL AND ON-TREATMENT ANALYSES MAY PRODUCE UNRELIABLE ESTIMATES WHEN THE EFFECT OF TREATMENT IS SMALL. INTERNATIONAL STANDARD RANDOMISED TRIAL NUMBER REGISTER: ISRCTN 81079604.	2014
