eQTL meta-analysis discovers more eQTL than individual cohorts. (a) Quantile-quantile plot of eQTL from individual cohorts as well as the meta-analysis of the true (black) and permuted (light blue) data. Number of significant eQTL (SNP-gene pairs) (b) or genes with significant eQTL (c) as a function of cohort size.
