Fig. 2From: Joint analysis of multiple blood pressure phenotypes in GAW19 data by using a multivariate rare-variant association testQuantile–quantile (Q-Q) plot for p values obtained by using MURAT and adjusted p values obtained by using SKAT to test 10,866 genes. The adjusted p values are defined as twice the minimum of the SBP and DBP-based p values obtained via SKATBack to article page
