Difference in mean percent weight change between commercial programs that dominate the market share (Weight Watchers; Jenny Craig; Nutrisystem) and comparators displayed by time point. Diamond size is standardized across trials and does not reflect sample size analyzed. Attrition reflects the percentage of participants unavailable for weight measurement at that time point in the trial. *Results from completers’ analysis. **Results reported in more than one article. Abbreviations: C – attrition reported in comparator arm at time point; DM – overweight or obese patients with diabetes mellitus; GEN – general population of patients with overweight and obesity; LC – low carbohydrate version of program; NR – not reported; P – attrition reported in commercial program arm at time point; T – telephone based program; WW – Weight Watchers.
