Signature based on molecular subtypes of deoxyribonucleic acid methylation predicts overall survival in gastric cancer

Figure 2 Cluster analysis for Deoxyribonucleic acid methylation classification and the corresponding heatmap. A: Delta area curve obtained from unsupervised clustering using 1061 Deoxyribonucleic acid methylation sites, which indicates the relative change in the area under the CDF curve for each category number k compared with k-1; B: Heatmap corresponding to the 1061 Deoxyribonucleic acid methylation sites in three clusters.
