NC-AE medication use at visit was used as the dependent (outcome) variable. Logistic regression analysis with exchangeable within-woman correlation was performed on all observations (visits) for all individuals. Odds ratios are shown with and without adjusting for HIV-positive status. RDU= recreational drug use. OR= odds ratio. aOR= adjusted odds ratio. CI= confidence interval.

^⋄= No alcohol use (abstain) was used as the reference for the other alcohol use categories.

^§= Visits at or subsequent to AIDS diagnosis.

^*= Analysis conducted on HIV-infected individuals only.
