Construction of immune-related gene pairs (IRGPs) model. A Prediction accuracy was evaluated by 10-fold cross-validation in the LASSO model. B One-year dependent ROC curve was plotted to calculate the optimal cutoff of risk score (red point). C Area under the curve (AUC) value for 1-year overall survival rate was calculated in the training set. D, E High-risk patients had lower overall survival rates than low-risk patients in both training (D) and test (E) sets. F, G The number of deaths was increased with the increasing risk score in the training (F) and test (G) sets. P<0.05
