Note. Negative binomial GEE model. Number of drinks was rounded to the nearest integer. Cohort 2 = 0, Cohort 3 = 1. Gender: Female = 0, Male = 1. Race/Ethnicity: Non-Hispanic white = 0, other = 1. Class Year: Freshman year = 0, Sophomore year = 1. Semester: Fall semester = 0, Spring semester = 1. Biweek of the Semester: Continuous variable, from biweek 1 to biweek 8. Day of the Week: Coded as 6 binary variables, with 0 for Sunday and 1 for the other day of the week. Pregaming: No pregaming = 0, Pregaming = 1.
