Numbers in parentheses represent standard errors; Reported adjusted odds ratio for controlled variables (i.e., age, female, Hispanic/Latino, academic level, receiving free lunch, ratio of room to people, parental drink, popularity, drinking exposure to friends, number of crowd identified with, and number of sports participated in) were estimated based on Model 1. Models control for school identifiers and dummy marker of activity participation.
