Note. N (days) = 6487, N (persons) = 207. Akaike Information Criteria (AIC) = 7582.70, Bayesian Information Criteria (BIC) = 8050.35. Gender is coded 0= women, 1 = men. Day of the week, elapsed day, and site are included as covariates but not depicted due to space limitations. Intox = Intoxication, Rel = Relationship, cntrl = control, RRR= relative risk ratio. Categories are mutually exclusive. The oral sex category refers to nights that oral sex but no intercourse occurred.
