Lifetime adulthood average heavy drinking frequency. Bolded entries are statistically significant results. Two separate models with different dummy codes were conducted to compare all possible contrasts across ADHD persistence, childhood ADHD only, and non-ADHD, but all results are presented together in this table because the effects of covariates were identical and to save space.
