n = 183. Values were determined by type II ANOVA for the analysis of weight loss as a function of initial weight, age, race, site, sex, prerandomization status, and compliance-adjusted assignment in a strictly additive model (no interactions allowed) under a “completers only” analysis. Compliance-adjusted assignment was not significant.
