and cumulative length of GWS loci are calculated on non-overlapping GWS loci. The percentage of the genome covered was calculated by dividing the cumulative of GWS loci by 3,039 Mb (the approximated length of the human genome).*The number of individuals in the trans-ancestry meta-analysis (n = 5,314,291) is smaller than the sum of ancestry-group-specific meta-analyses (n = 5,380,080) because of variation in per-SNP sample sizes for SNPs included in the final analysis.
