^aP-values are based on ANOVA for age, AUDIT, quantity, frequency, binge occasions, average eBAC, and peak eBAC; Pearson’s chi-square was used for gender and % over the weekly recommended level.
^bEstimated average percentage BAC per week.
^cEstimated average peak percentage BAC during the past month.
