Outcome: homeless at discharge
No. of days drinking in the 30 d before program admission	0.99 (0.98, 0.99)	< .001	0.5
No. of days employed in the 30 d before program admission	1.01 (1.01, 1.02)	< .001	0.2
Past hospitalization for alcohol abuse	1.16 (1.07, 1.26)	< .001	0.1

Race	1.09 (1.00, 1.18)	0.04	0.1
Outcome: employed at discharge
VA financial support	3.05 (2.67, 3.48)	< .001	5.0
No. of days drinking in the 30 d before program admission	1.02 (1.02, 1.03)	< .001	0.9
No. of days employed in the 30 d before program admission	0.98 (0.97, 0.99)	.001	0.2
No. of reported medical problems	0.96 (0.94, 0.99)	.001	0.1
Past hospitalization for drug abuse	0.84 (0.76, 0.94)	.005	0.1

Note. CI = confidence interval; OR = odds ratio; VA = Veterans Affairs. Analyses used forward stepwise method of entry with Wald. McKelvy–Zelvoina R² provides an estimate of the percent of variance in the outcome measure explained by the predictor variable (e.g., 0.6 = 0.6 of 1%; 10.3 = 10.3%).
