Fig. 4. Longitudinal models of polygenic associations with alcohol use and misuse.
Predicted values for alcohol use index (AUI) from ages 12 to 32 using linear mixed models in Add Health (N = 5107). Values for EXT and ALCP-specific polygenic scores set to ±1.5 SD. The shaded areas represent 95% confidence intervals. Confidence intervals estimated using percentile method bootstrapping over 1000 bootstrap samples. All other covariates set to mean values.
