¹Number chromosomes harboring interaction eQTL hotspots.

^2–3Percentage of interaction eQTL for which there was a significant eQTL at the ²covariate position or ³peak position in the original eQTL mapping analysis (no covariate).

⁴Percentage of interaction eQTL for which there was a significant interaction eQTL with the covariate and peak positions reversed.
