Enrichment of cLD among pairs of genes in chromatin contact regions.

a) The comparisons of cLD values between the 3D chromatin interaction regions and non-interaction regions among 13 different distance groups in the European population. (Other populations are shown in Fig D in S1 Text) The confidence intervals for these bars are presented in Table I in S1 Text. b) The same comparisons using standard LD in the European population. (Other populations are shown in Fig E in S1 Text) c-e) The ratios between the number of gene pairs in 3D chromatin interaction regions against the number of gene pairs that are not in 3D regions. The x-axis is the cLD value cutoffs above which the gene pairs are counted. c) European population. d) African population. e) East Asian population.
