  1. Logistic regression model; regression coefficient, standard error of estimate (SE), Wald test, odds ratio and 95% confidence interval (CI) (n = 2105).
  2. Notes: Gender was coded 0 for women and 1 for men. Age was a continuous variable. There were no gender differences in the association between intoxication frequency and risk of alcohol related injury (the interaction term was close to zero (0.002, p = .729).
