NM gene exons, lincRNA exons and background loci. The number of tested SNPs per platform was scaled by the fractional contribution of Illumina (58.6%) versus Affymetrix (41.4%) platforms to the full set of GWASs in the NHGRI GWAS catalog [1]. The number of trait-associated SNPs per tested SNP was then determined using this scaled number of tested SNPs. Fisher's exact test was used to calculate P values and error bars in Figure 4 represent 95% binomial proportion confidence intervals.
