CRP and coronary artery disorder: Scatter plots for the example of CRP and CAD risk are given in Figure 4; the plot using variants from the CRP gene region (left) demonstrates homogeneity of estimates, whereas the plot using genome-wide significant variants (right) demonstrates heterogeneity, with several clear outliers (although the genetic variants in the CRP gene region are partially correlated, so the homogeneity in the first case is somewhat artifactual).
