Mean difference in weight change across all included studies, intervention versus control, systematic review of weight loss in short-term interventions (N = 14) for physical activity and nutrition among adults with overweight or obesity. Meta-analysis was of the effects of intervention versus control on mean difference in weight change (kg) among the 14 included studies. Values less than 0 indicate an intervention effect (ie, favors intervention), and values greater than 0 indicate no intervention effect (ie, favors control). Abbreviation: DL, DerSimonian and Laird’s Q test (22).
