Table 2:

Comparison of change outcomes in any API versus control (primary aim, N=891)

	Ratio of follow-up 1 to baseline				Ratio of follow-up 2 to baseline
	API R/OR (SE)	Control R/OR (SE)	Ratio of ratios (95% CI)	P-value	API R/OR (SE)	Control R/OR (SE)	Ratio of ratios (95% CI)	P-value
Primary outcome
Binge drinking frequency/month (R)	1.68 (0.14)	2.00 (0.24)	0.84 (0.63, 1.12)	0.243	2.42 (0.20)	2.46 (0.30)	0.98 (0.73, 1.32)	0.901
Secondary outcomes
Alcohol consequences (R)	1.64 (0.09)	1.90 (0.17)	0.87 (0.70, 1.07)	0.187	0.89 (0.08)	1.02 (0.13)	0.88 (0.64, 1.21)	0.422
Health services utilization (OR)	1.96 (0.22)	2.29 (0.36)	0.86 (0.59, 1.25)	0.427	1.36 (0.16)	1.29 (0.20)	1.05 (0.74, 1.51)	0.775

Note: Ratios (R) and odds ratios (OR) are shown for log-link and logit-link models, respectively. P-values test the null hypothesis of no difference-in-difference between groups on the log scale or, equivalently, that the ratio of ratios is 1. The comparison that corresponds to the study’s primary hypothesis is shaded in gray.
