Constructing an immune risk score predictive model using the training set. (A) Kaplan–Meier curves for OS outcomes in the training cohort grouped into high- and low-risk score groups. (B) Time-dependent ROC curves for prediction of 1-, 3-, and 5-year survival outcomes. (C) Distribution of risk scores of the training cohort. (D) Vital statuses for patients in high- and low-risk patients. (E) Expression patterns for 14 immune-associated genes in high- and low-risk score cohorts. (F) A nomogram for the estimation of 1-, 3-, and 5-year OS probabilities in the training cohort. Risk scores and other independent prognostic factors are incorporated in the model. (G) Time-dependent ROC curves for the prediction of 1-, 3-, and 5-year survival rates using the nomogram. (H) Calibration plot of nomogram in the training cohort according to the agreement between predicted and observed 1-, 3-, and 5-year outcomes. The model’s ideal performance is shown by dashed lines. (I) Decision curve analysis for 1-, 3-, and 5-year risk using the nomogram. Black line represents the hypothesis that no patient died at 1-, 3-, and 5-years.
