The NRG signature for predicting survival in the training and validation cohorts of LUAD. (A) The distribution and survival status of tumors with LUAD for the NRG signature. (B) Kaplan–Meier survival curves between the high-risk and low-risk groups (P < 0.001). (C) Time-dependent ROC analyses at 1, 3, and 5 years in the training set (sensitivity = 0.62, specificity = 0.56, positive predictive value (PPV) = 0.4, negative predictive value (NPV) = 0.75, and accuracy = 0.58) and the validation set (sensitivity = 0.63, specificity = 0.56, PPV = 0.36, NPV = 0.79, and accuracy = 0.58)
