Measured Weight Gain Across Treatment Arms

Variable	Standard (M, SD)	Extended (M, SD)	β	95% CI	p
Measured Weight (pre-treatment to week 24)	10.37 (8.86)	5.83 (9.11)	−4.76	−7.68 to −1.84	0.002
Measured Weight (week 8 to week 24)	4.69 (5.44)	2.52 (6.72)	−2.31	−4.39 to −0.23	0.03

Note. β = beta weight; CI = Confidence Interval; the models included main effects for the treatment arm and gender, baseline smoking rate, and previous weight as covariates.
