Notes: The first two columns show estimates of adjusted odds ratios (adjusted for all associated factors variables listed in the table) separately for private and public university students, in multivariable binary logistic regressions. The last column shows the estimates for the entire sample, adding the “Private university” dummy (binary) variable to the regression. 95% CI shown in square brackets. Reference categories: Female, Ages 18-19, No car, Lives in dormitory, and Scholarship. *** p<0.01, ** p<0.05, * p<0.10
