Figure 4.
Mean difference in weight change, systematic review of weight loss in short-term interventions (N = 14) for physical activity and nutrition among adults with overweight or obesity, sensitivity analysis removing studies with high attrition, intervention versus control. Meta-analysis was of the effects of the intervention versus control on mean difference in weight change (kg), removing the studies with high attrition (24–26,30,33,35–37) as a sensitivity analysis. Values less than 0 indicate an intervention effect (ie, favors intervention), and values greater than 0 indicate no intervention effect (ie, favors control).
