Table 1 reports descriptive statistics for all covariate predictors measured at the baseline assessment (~age 20). In addition to the demographics described above, this subsample had a mean LR score of −.47 which reflects a lower average LR than would be expected since LR was converted to z-score at baseline for the full sample. 40% of the probands had a parent meet criteria for AUD at T1. These subjects had an average of less than 3 drinks per drinking occasion at T1, and an average onset of drinking at ~15 years. The mean BMI was 22 (in the “normal weight” range), and mean age ~23 years at T1. A third of the sample met criteria for AUD by the T25 followup assessment.
