Construction of a prognostic risk scoring model. (A) Coefficient distribution and error distribution of LASSO regression. (B) Heatmaps of the expression of five genes included in the risk score model. (C) Survival time and status profiles of patients with varying risk scores. (D) and (F) Kaplan-Meier survival analysis was performed to calculate the OS of high-risk and low-risk groups patients in the TCGA dataset. The ROC curve was used to verify the ability of the risk model to judge the 1-, 3-, and 5-year OS rates of patients in the TCGA. (E) The nomogram, including risk scores and clinical features, showed the prognosis estimates of the cases in the TCGA database. ns, nonsignificant, *P < 0.05, **P < 0.01, ***P < 0.001, ****P < 0.0001
