Prognostic and Immunological Significance of the Molecular Subtypes and Risk Signatures Based on Cuproptosis in Hepatocellular Carcinoma

Figure 6

Formation of the risk score signature utilizing five CRGs in the TCGA. (a) Univariate Cox regression analysis selected six CRGs. (b, c) Detection of five prognostic CRGs using the LASSO Cox regression analysis. (d) Heatmaps of the five prognostic CRGs according to the distribution of risk scores. The color legend represents the log2 (FPKM) value. (e) The distribution of risk scores. (f) Patients’ survival status according to the distribution of risk scores. (g) Kaplan-Meier survival analysis compared the OS between the high-risk and low-risk groups. (h) Kaplan-Meier survival analysis compared the PFS between the high-risk and low-risk groups. (i) The ROC curves for 1, 3, and 5 years of the risk model. (j) Mutation landscape of the five CRGs of the risk model.
