Table 1.

Original analysis of grams of alcohol consumer per week at follow-up compared between the intervention and control groups. When removing three potential outliers, the difference was marginally statistically significant.

	Intervention group (n=402), mean (SD)^a	Control group (n=529), mean (SD)^a	Incidence rate ratio^b (95% CI)	P value
Weekly alcohol consumption (g/wk)^b	113.4 (81.1)	120.8 (86.4)	0.937 (0.861-1.019)	.13
Sensitivity analysis excluding three outliers	107.4 (73.4)	119.1 (81.3)	0.921 (0.848-1.000)	.049

^aMean and SD given by negative binomial regression.

^bIncidence rate ratio given by negative binomial regression (adjusted for sex, age, university, and frequency of heavy episodic drinking at baseline).
