The first study will be loaded into the comparison view as the root, with reported loci at genome-wide significance plotted by position. Studies for comparison can be loaded into the view using the drop-down menu. Only studies with at least one overlapping locus will be displayed as an option for comparison. Studies in the drop-down are ordered decreasing on number of overlaps with the loaded root. When >1 study is loaded, intersecting loci across all of the loaded studies are displayed in red both on the intersection bar at the top of the view, and within each study. Loci within each study which overlap with the root study are displayed black. Non-overlapping loci are plotted grey.
