Details on the four training genome-wide association studies (GWAS) datasets are provided in the Methods section. LDSC: linkage disequilibrium score regression using genome-wide summary statistics (Supplementary Table S10); rg genetic correlation. RRHO: rank–rank hypergeometric overlap test showing the relative overlap of genome-wide summary statistics (Supplementary Table S11). Sign tests one-sided binomial sign tests for CCS GWAS p value thresholds p < 0.05 and p < 1 × 10−5 and the corresponding probability of success (Supplementary Table S12). PGS association of polygenic scores with the CCS; pT training GWAS data p value threshold; effect size linear regression effect size at the pT showing the strongest support for an association (see Supplementary Table S13 for results of all ten thresholds); p value: one-sided p value not corrected for multiple testing. The significance level adjusted for multiple testing was α = 0.05/(10 × 4) = 0.00125.
