Summary of Findings The examination of the meta-analyses showed that: 1) The results in Figures 3 and 4 do not match the methods and figure captions. 2) Of the 48 studies qualitative analysis, the SR authors report excluding 10 studies from the meta-analysis but one of these studies was included in the meta-analysis. 3) The data used for one of the studies in Figures 3 and 4 do not match the report in the original study. 4) The re-analyzed data contrasts with the review’s conclusion that BMI and BMI z-score were significantly reduced in the intervention group.
