Distribution of mean LD score and level of replicate tagging for SNPs in high- and medium-density panels. a The mean LD score is used to represent the regional LD, which was fitted by segment with an average length of 100 kb using a sliding window approach, and the LD score of each SNP is calculated as the sum of the LD \({r}^{2}\) values for the target SNP and all SNPs within the 10-Mb region centered on the target SNP. b The level of replicate tagging was calculated using the LDAK software to show that SNPs were repeatedly tagged due to LD
