Figure 3. Univariate survival analysis of the hub genes was performed using the Kaplan-Meier curve. (A and C) The expression of AURKA gene showed significantly poorer DFS and OS in HCC samples (Log rank P <0.05). (B and D) The expression of the CDC20 gene showed a significantly poorer OS and DFS in HCC samples (Log rank P <0.05). Abbreviation: DFS, disease-free survival; OS, overall survival; HCC, hepatocellular carcinoma.
