Fig. 2From: Comparison of different functional prediction scores using a gene-based permutation model for identifying cancer driver genesQuantile–quantile (QQ) plots of p-values comparing the observed distribution of p-values (y - axis) to the expected p-values of a null distribution (x - axis) for 19,835 breast cancer genes (Panel a) and 20,047 lung cancer genes (Panel b). The red line represents the expectation under the null. The grey area depicts the 95% confidenceBack to article page
