We identified 18,210 eQTSs (FDR<0.05) representing 689 unique traits (55% of tested traits) and 2,568 genes (13% of tested genes; Supplementary Data 5, Figure 1d). Of these genes, 719 (28%) were not identified in the trans-eQTL analysis, emphasizing the value of analyzing eQTS in addition to trans-eQTLs (Figure 6a–b). Median eQTS effect sizes were smaller than for cis-eQTLs and similar to trans-eQTLs (median r=0.037; Supplementary Figure 8a, e, i).
