Building the prognostic model and nomogram. a, b The process of LASSO regression which added a penalty term for shrinkage of the parameter estimates to the least-squares loss function; c–f the ROC of prognostic model and clinical features for 5-years OS in the training set (c, e) and validation set (d, f); g the nomogram based on clinical features and prognostic model for OS of patients with LUAD. The red highlights showed that the total point of the patient with LUAD who was Stage IV was 48.8 and the probability of survival time of the patient less than 1, 3, 5 years was 0.212, 0.635, 0.894, respectively
