Findings reveal a lack of reporting of intervention details , the need to report a disease-specific rationale for selection of the particular yoga style used for the intervention , and that a limited number of yoga styles have been investigated in persons with fibromyalgia
OBJECTIVE The objective of this article was to present a methodology incorporating existing guidelines and tools for systematic review s and to evaluate the Delphi survey 33 key component recommendations of yoga interventions for musculoskeletal conditions as a tool for a systematic review in fibromyalgia studies .
Testing a tool for assessing the risk of bias for nonrandomized studies showed moderate reliability and promising validity.
OBJECTIVES To develop and vali date a new risk-of-bias tool for nonr and omized studies ( NRSs ) . STUDY DESIGN AND SETTING We developed the Risk of Bias Assessment Tool for Nonr and omized Studies ( RoBANS ) . A validation process with 39 NRSs examined the reliability ( interrater agreement ) , validity ( the degree of correlation between the overall assessment s of RoBANS and Method ological Index for Nonr and omized Studies [ MINORS ] , obtained by plotting the overall risk of bias relative to effect size and funding source ) , face validity with eight experts , and completion time for the RoBANS approach . RESULTS RoBANS contains six domains : the selection of participants , confounding variables , the measurement of exposure , the blinding of the outcome assessment s , incomplete outcome data , and selective outcome reporting . The interrater agreement of the RoBANS tool except the measurement of exposure and selective outcome reporting domains ranged from fair to substantial . There was a moderate correlation between the overall risks of bias determined using RoBANS and MINORS . The observed differences in effect sizes and funding sources among the assessed studies were not correlated with the overall risk of bias in these studies . The mean time required to complete RoBANS was approximately 10 min . The external experts who were interviewed evaluated RoBANS as a " fair " assessment tool . CONCLUSIONS RoBANS shows moderate reliability , promising feasibility , and validity . The further refinement of this tool and larger validation studies are required
