We ran separate logistic regression models with each of the FH measures as predictors along with assessment-age, gender, and self-reported race/ethnicity, included as covariates. In all models, lifetime diagnosis of DSM-5 AUD was included as a binary outcome variable. For age of onset of regular drinking and parietal P3 amplitude, we ran separate linear regression models with each of the FH measures as predictors along with assessment-age, gender, and self-reported race/ethnicity, included as covariates. Age of onset of regular drinking and parietal P3 amplitude for visual target stimuli were included as continuous outcome variables in respective models.
