Covariates predicting outcome measures using generalized estimating equation (GEE) models

	Days Worked	ASI Legal	Peak density	Abstinence

	Coef (S.E)	Coef (S.E)	Coef. (S.E)	OR_adj (95% CI)

12-step involvement scale	ns	−0.01(0.01) ^a	−1.27(0.42) ^b	1.25(1.02–1.54) ^a
Drinking status of social network	ns	ns	3.10(1.57) ^a	ns
Drug status of social network	−22.65(7.62)^b	ns	4.71(1.60)^b	ns

Note: Coefficients and odds ratios have been adjusted for time of interview, age, race, and education.

Days Worked, Peak Density, Abstinence and Arrests assess the past 6 months. ASI variables measure past 30 days.
