Descriptive data, shown in Table 3, provide the demographics (sex, marital status, and race) and baseline characteristics by latent class (see Supplemental Figure 1). Inferential analyses using multinomial logistic regression were conducted to examine the association between each of the baseline predictors and the odds of expected classification in a given class as compared to each other class. For the purposes of the current study we were particularly interested in the probability of the low risk drinking classes versus all other classes, specifically we focused on Class 5 “consistent low risk drinking” (Figure 1) and Class 6 “abstinence-to-low risk drinking” (Figure 2) as the reference classes. Supplemental Figures 2–6, provide the associations between predictors and odds of expected class membership with all other classes as reference classes.
