§

Baseline= time point immediately following randomization into weight loss maintenance intervention.

*

Dropouts are assumed to have regained 0.3 kg per month.

Weight change was computed as participant’s weight at end of weight loss maintenance intervention (6–month follow-up) minus their weight at the beginning of weight loss maintenance intervention (baseline). Successful weight maintenance was defined as weight change remaining below the upper limit of the Δ indifference region (3% mean baseline weight), ΔPLP=−3.20 to +3.20 kg, ΔSBP=−2.98 to +2.98 kg.

Logistic regression model, RIR adjusted for sex and community organization.
