Physical Activity Interventions And Chronic Diseases: A Matched-Pair Analysis Comparing Cochrane And Non-Cochrane Systematic Reviews
Related Research units
Abstract
METHODS: This is a substudy of an overview of 56 Cochrane reviews with RCTs of physical activity interventions for chronic diseases (cancer; cardiovascular, respiratory, renal diseases; metabolic, mental, musculoskeletal disorders). A matched-pair analysis was chosen to contrast Cochrane and non-Cochrane reviews. A systematic literature search was undertaken to identify non-Cochrane reviews that matched based on intervention, condition, outcomes and publication year as in the corresponding Cochrane reviews. Methodological quality of the reviews was assessed using AMSTAR. The pairs will be contrasted in terms of frequency and degree of concordance in their results and whether differences affected the citation rate.
RESULTS: Of the 56 Cochrane reviews within our data set, we found 33 non-Cochrane reviews that met the eligibility criteria. The full analysis will be completed by the end of 2016 and final results will be presented fully for the first time at the ACSM meeting.
CONCLUSION: This is the first study comparing systematic reviews that were conducted within and outside the Cochrane Collaboration, in particular with respect to physical activity interventions for chronic diseases. Unlike a previous study using meta-analyses on medication therapy within the cardiovascular literature, we applied a more precise methodological approach that concurrently points out how differences can be explained. The findings of our study should make an important contribution to the field of evidence-based physical activity and emphasize that a critical appraisal of systematic reviews reporting physical activity interventions is highly recommended for health professionals.
