You are the third person to mention that the cohort is "dieters who regain weight". Reading the article and its referenced study, I thought the cohort was "all who were included in the non-placebo group of the RCT" and that the average was taken over all such subjects. I've tried, can't find any evidence to the contrary. I am wrong and missing some key claim in the study? I would appreciate if you could support your claim. |

> Weight regain data are expressed as weight change from baseline (pre-intervention) or difference in weight change from baseline between intervention and control for randomised controlled trials. When analysing and presenting data from all studies, we used weight change from single arm trials, observational studies, and the intervention groups from randomised controlled trials. When analysing data from randomised controlled trials only, we calculated the difference in weight change between the intervention and control groups at the end of the intervention and at each available time point after the end of the intervention. When studies had multiple intervention arms, we treated each arm as a separate arm and divided the number in the comparator by the number of intervention arms to avoid duplicative counting.19
