Distribution of adjusted p-values for Illumina, Affymetrix RMA, and Affymetrix QN. P-values have been adjusted for multiple testing via the Benjamini and Hochberg method. Prior to adjusting for multiple testing, the distributions were similar in appearance with a lower density of Illumina p-values near 0 compared to Affymetrix. The relatively lower density of Illumina adjusted p-values near 0 explains why there are many more differentially expressed genes in Affymetrix compared to Illumina.
