Validating the model in validation set. A Nomogram for the Cox proportional hazards model in GSE63155. B KM plot for high and low risk score groups in GSE63155. C Scatter plots for the survival characteristics of patients with increasing risk score and heatmap for the expression of final genes in patients with increasing risk score: the vertical dashed lines divided the samples into high and low score group, left side referred to high score group, right side referred to low score group. Calibration of nomogram for 1-year (D), 3-year (E), 5-year (F) in GSE63155: x-axis referred to the predicted probability of overall survival by the model, y-axis referred to the actual probability of overall survival, the diagonal (dashed line) referred to the ideal status that the predicted survival rate equaled to the survival rate, the blue solid line referred to the actual status of the predicted and actual survival rate. G Time-dependent ROC curve of the model in GSE63155: x-axis equaled to 1—specificity of the model, y-axis was the sensitivity of the model. (H) 5-year DCA in GSE63155: x-axis referred to threshold probability for treatment or intervention, y-axis referred to the net benefit. Green line stood for no treatment for all samples, the net benefit was 0. Red line stood for treating all samples with the assumption of all samples would die within 5 years. Blue line stood for treating samples by the prediction of the model
