Results of multivariable logistic regression analysis to predict weight loss response.

Variable	OR	95 % CI	P
Treatment Group (Sibutramine alone)			0.07
Sibutramine + brief lifestyle	1.41	0.56 – 3.64	0.47
Sibutramine + lifestyle modification	3.66	1.44 – 10.88	0.01
Lifestyle modification alone	2.23	0.96 – 6.41	0.09
Ethnicity (Caucasian)	0.58	0.23 – 0.97	0.04
Distance from clinic	1.02	0.99 – 1.04	0.29
Years since onset of overweight	1.01	0.98 – 1.05	0.39
BDI-II score	0.95	0.90 – 0.997	0.04
Weight loss at week 3 (% of baseline weight)	1.73	1.33 – 2.27	<0.001

OR = Odds ratio, CI = Confidence interval. Treatment group and ethnicity are categorical variables and reference groups are listed in parentheses. Distance from clinic, 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.
