Descriptives are calculated at the event-level. All P-values are calculated using univariate mixed effects models for each characteristic with participant as a random effect. P-values are presented as P-value (test statistic).
AUD, alcohol use disorder (Diagnostic and Statistical Manual of Mental Disorders, fourth edition abuse or dependence); BMI, Body Mass Index; Imp con, impaired control; MJ marijuana; SR drinks, self-report number of drinks.
