Longitudinal trajectories of insomnia, hypersomnia, and variability in sleep duration (absolute value) in individuals with and without AUDs at baseline. All individuals were adolescents (mean age = 16.23, range = 12–19 years) at the baseline visit. Data points reflect the estimated means, accounting for covariates including age, sex, and current alcohol symptoms, and error bars are the 95% confidence intervals. Significant group differences by year according to post-hoc comparisons are noted (ns: p > 0.5; *: p < 0.05; **: p < 0.01; ***: p < 0.001).
