Three gene clusters based on prognostic differential gene expression levels. (A) Heat map. Prognostic differential genes were upregulated in gene Cluster C and down-regulated in gene Cluster A. (B) Kaplan-Meier survival curves. p < 0.001. (C) PCA plot. Blue dots represent patients in gene Cluster A; yellow dots represent patients in gene Cluster B; red dots represent patients in gene Cluster C.
