The prevalence of each alcohol use measure for each target sample is shown in Table 1. The SNP-heritability of AUDIT-C was 11%, while the SNP-heritability of the AUDIT-P score was 9%, and the genetic correlation (i.e., SNP-rg) between them was rg = 0.70 (as reported in the original paper (Sanchez-Roige et al., 2018)). See Supplemental Table 15 for the number of SNPs in each PRS threshold.
