Construction and validation of a novel prediction system for detection of overall survival in lung cancer patients

Figure 4 Construction of a prognostic predictive model using real hub genes. A: Area under the curve measurement performed to select the optimal candidate genes for the scoring system construction; B: Receiver operating characteristic curve showing the prediction efficiency of the scoring system in the training, test, and all dataset; C: Risk-score served as an independent risk factor in predicting patients’ survival; D and E: Development of nomograms and calibration curves for prognosis in the total dataset.
