The results showed that EZH2 was differentially expressed between the HCC group and normal groups (TCGA normal and GTEx data) (P < 0.01), and the EZH2 low-risk group was significantly outperformed high-risk group in terms of both DFS (P < 0.001) and OS (P < 0.001), as shown in Fig. 2d and e. Here, EZH2 is linked to hepatocellular carcinoma.
