Table 5.

Odds ratios and 95% confidence intervals for the effects of predictors on abstinence from heavy drinking in logistic regression analyses in COMBINE and in PREDICT.

	Predictor	Categories	COMBINE TS	COMBINE VS	PREDICT
Predictors from tree analyses	CDA	Longer vs. Shorter¹	3.97 (2.59, 6.09)^*	2.39 (1.37, 4.15)^*	1.60 (1.09, 2.35)^*
	Age	Older vs. Younger²	2.08 (1.36, 3.20)^*	1.70 (1.09, 2.64)^*	1.21 (0.82, 1.78)
	Age (among shorter abstinence)	Older vs. Younger²	2.51 (1.83, 3.45)^*	1.61 (0.58, 4.43)	1.13 (0.65, 1.97)
	Age (among longer abstinence)	Older vs. Younger²	1.73 (0.78, 3.83)	1.65 (0.95, 2.87)	1.29 (0.76, 2.20)
Predictors from deterministic forest analyses	CDA	Longer vs. Shorter¹	3.73 (2.40, 5.78)^*	2.18 (1.24, 3.81)^*	1.63 (1.11, 2.40)^*
	Age	Older vs. Younger²	2.43 (1.80, 3.28)^*	1.40 (0.92, 2.13)	1.16 (0.75, 1.65)
	Drinking goal	Complete abstinence vs. other goals	1.97 (1.45, 2.66)^*	1.71 (1.14, 2.57)^*	1.71 (1.14, 2.55)^*

In COMBINE “longer” means “> 14 days”, in PREDICT “longer” means “> 21 days”.

In both data sets “older” means “> 45 years”.

Effects are significant at 0.05 level.
