aAUDIT scores were collected at recruitment to the parallel ongoing study B, 6 weeks before recruitment to study C
b P values are based on ANOVA models for AUDIT, age, quantity, frequency, binge occasions, average eBAC, and peak eBAC while Pearson’s chi-square statistic was used for the proportion of women
cEstimated average percentage per week
dEstimated average peak percentage Blood Alcohol Count (BAC) within the past month
