instead to keep the lead SNP (cross-ancestry fine mapping will only analyze the SNPs common in analyzed ancestries). Next, because the credible set length identified is related to the number of variants in the input, to provide a more direct comparison between the cross-ancestry fine mapping and the fine mapping using information only from EUR, we used the same lists of SNPs from the above 92 regions in the cross-ancestry fine mapping as for the EUR-only fine mapping. ‘Credible set’ was defined as plausible causal variants with accumulated PIP >99%. For each credible set, we report the variant with the highest PIP. We assumed that each locus contains only one causal variant by default, and increased to three at maximum if the analysis was unable to converge.
