Supplementary Figure 5: Sharing between mQTL and eQTL vs. window sizes.
From: An xQTL map integrates the genetic architecture of the human brain's transcriptome and epigenome
π1 statistics used for assessing xQTL sharing. As the window size for testing mQTL decreases, which by construction reduces the number of mQTL SNPs, the π1 of eQTL p-values associated with the mQTL SNPs is found to increase.
