aSDs calculated directly from the reported confidence intervals; bAdditional unpublished data provided; cWhere change SDs were not explicitly reported, they were calculated from the reported baseline and final SDs using the correlation method advocated in the Cochrane handbook [32],[33] – correlation coefficient calculated directly from the empirical data presented in Christensen [55]; dSDs calculated directly from the reported p-value; NR = Not reported; *A minus figure indicates mean difference in body weight change in favour of intervention.
