Interpreting Meta-Analyses of Genome-Wide Association Studies
P-M plots of the Crohns disease meta-analysis results of Franke et al. .
Two of six associated loci showing high heterogeneity are plotted. See Figure S1 for the plots of all six loci. The names of the studies follow Franke et al. . The dashed horizontal line shows the genome-wide significance threshold. The dotted vertical lines show the prediction regions based on m-value.
