Heatmaps of DM CpG sites located in CpG islands (A) and the TSS200 region of genes (B). The rows correspond to CpG sites, while the columns correspond to samples. Case samples are blue, and controls are green. The color of each cell in the heatmap is based on the Beta (β) value of the corresponding CpG site in the corresponding sample, with colors ranging from red (β = 0) to blue (β = 1). The ordering of CpG sites and samples in the heatmaps was determined via unsupervised hierarchical clustering.
