Optimal Strategies for Reporting Pain in Clinical Trials and Systematic Reviews: Recommendations from an OMERACT 12 Workshop
Objective . Pain is a patient-important outcome , but current reporting in r and omized controlled trials and systematic review s is often suboptimal , impeding clinical interpretation and decision making . Methods . A working group at the 2014 Outcome Measures in Rheumatology ( OMERACT 12 ) was convened to provide guidance for reporting treatment effects regarding pain for individual studies and systematic review s. Results For individual trials , authors should report , in addition to mean change , the proportion of patients achieving 1 or more thresholds of improvement from baseline pain ( e.g. , ≥ 20 % , ≥ 30 % , ≥ 50 % ) , achievement of a desirable pain state ( e.g. , no worse than mild pain ) , and /or a combination of change and state . Effects on pain should be accompanied by other patient-important outcomes to facilitate interpretation . When pooling data for meta analysis , authors should consider converting all continuous measures for pain to a 100 mm visual analog scale ( VAS ) for pain and use the established , minimally important difference ( MID ) of 10 mm , and the conventionally used , appreciably important differences of 20 mm , 30 mm , and 50 mm , to facilitate interpretation . Effects ≤ 0.5 units suggest a small or very small effect . To further increase interpretability , the pooled estimate on the VAS should also be transformed to a binary outcome and expressed as a relative risk and risk difference . This transformation can be achieved by calculating the probability of experiencing a treatment effect greater than the MID and the thresholds for appreciably important differences in pain reduction in the control and intervention groups . Conclusion . Presentation of relative effects regarding pain will facilitate interpretation of treatment effects
