Measures of alcohol consumption: means (SD)
AUDIT score (scale 0–40)	10.444 (3.716)	11.169 (4.257)	< 0.001

Average eBAC^b per week	0.161 (0.133)	0.198 (0.187)	< 0.001
Peak eBAC^c within past month	1.240 (0.760)	1.319 (0.897)	0.063

^aP-values are based on student’s t-test for age, AUDIT, quantity, frequency, binge occasions, average eBAC, and peak eBAC; Pearson’s chi-square was used for gender and % over weekly recommended level.
^bEstimated average percentage BAC per week.
^cEstimated average peak percentage BAC during the past month.
