Table 5. Fisher’s exact test reveals that mRNA are less likely to have an eQTL when they correspond to a differentially expressed gene (odds ratio 0.79, 95% CI 0.73–0.87, P < 0.001).

		Differential expression
		mRNA
		Yes	No	eQTL
eQTL	Yes	3541	1253	42%
	No	5133	1450	58%
		miRNA
		Yes	No	mirQTL
mirQTL	Yes	24	9	13%
	No	171	42	87%

A stronger but nonsignificant trend is observed with miRNA.
