OR = Odds ratio, CI = Confidence interval. Treatment group, education, and general feelings about self are categorical variables and reference groups are listed in parentheses. Age, years since onset of overweight, BDI-II score, and weight loss at week 3 are continuous variables, and the odds ratios refer to one unit increases.
