Weight loss progress, attendance, and drop-out at weeks 4–8 of behavioral weight loss treatment among women with obesity and depression whose weight loss was on target at week 3 of treatment (N=43)

Week of treatment	Weight loss not on target, N (%)	Weekly attendance, N (%)	Drop-out, N (%)	Clinically significant weight loss at 6 months, by early-treatment weight loss
				Se, %	Sp, %	5% or greater weight loss at 6 months among those whose early- treatment weight loss was on target N (%)	5% or greater weight loss at 6 months among those whose early-treatment weight loss was not on target N (%)	Crude RR (95% CI)	Adjusted RR (95% CI)

Se: sensitvity, i.e., proportion of women failing to achieve 5% or greater weight loss at 6 months who were not on target with their weight loss at a given week early in treatment; Sp: specificity, i.e., proportion of women achieving 5% or greater weight loss at 6 months who were on target with their weight loss at a given week early in treatment.
