1
Past-year non-drinking is modeled as the non-event
2
No trauma exposure is the reference category for the gender-specific odds ratio.
Notes:
OR=Odds ratio; IOR= Interaction Odds Ratio; CI=confidence interval; PTSD=post-traumatic stress disorder
Model covariates include any past-year mood disorder, any past-year anxiety disorder, any past-year drug use disorder, past-year nicotine dependence, age, race, education, marital status, employment status, and household income.
