Notes: College site was included as a covariate. Gender: male = 0, female = 1. Race/ethnicity: non-Hispanic White = 0, other = 1. Semester: fall = 0, spring = 1. Biweek of semester coded: 1–8. Number (no.) of drinking days, drinks per drinking day, and average (avg.) estimated blood alcohol concentration (BAC) in Models 2–4 were per-week averages. Estimated BAC was multiplied by 10. Model 2 includes all variables from Model 1 as covariates. Models 3 and 4 include variables from Model 1 and 2 as covariates.
For the first data row (total number of consequences), a Poisson distribution was used, so coefficients are incidence rate ratios with confidence intervals. For the individual consequences, a binomial distribution was used, so coefficients are odds ratios with confidence intervals.
