Heatmap analysis of 27 highly differentially methylated CpG-sites (delta beta ≥ 0.40 or delta beta ≤ -0.40 with FDR-adjusted p<0.05) between great saphenous veins (GSV) and internal mammary arteries (IMA).

<p>Regions shaded blue in the heat map represent hypomethylated regions, regions shaded red represent hypermethylated regions. The top black rectangles shows columns representing CpG-sites located inside CpG-island. Gene symbols and CpG-site IDs are shown on the bottom. Sample IDs are on the right.
