Table 2.

Comparison of joinpoint model with and without alcohol policies with Likelihood ratio test of significance (two-tailed, p value), by age group.

Age groups	Joinpoint with policies		Joinpoint without policies		p value
Age groups	AIC	R²-adjusted	AIC	R²-adjusted	p value
20+	1255.932	0.854	1268.47	0.837	p = .0003
20–29	868.94	.76	874.78	.75	p = .0073
30–39	1029.55	.68	1033.64	.67	p = .018
40–49	1203.73	.80	1204.53	.80	p = .091
50–59	1412.38	.87	1417.80	.87	p = .0090
60–69	1607.69	.80	1613.06	.80	p = .0092
70–79	1919.41	.76	1936.84	.74	p < .0001
80+	2490.16	.69	2531.68	.68	p = .0001

Lower AIC indicates a better model fit.
