Development and validation of a prognostic prediction model for alpha-fetoprotein-negative hepatocellular carcinoma with microvascular invasion after surgery

Figure 3 Prediction performance of the TGN scoring model based on receiver operating characteristic curve analysis and calibration curve analysis. Area under the curve values of the TGN scoring model, tumor burden score, gamma-glutamyl transpeptidase and white blood cells, neutrophil-to-lymphocyte ratio, and Barcelona Clinic Liver Cancer in the training and validation cohorts. Calibration curves demonstrated high concordance between TGN predicted and observed overall survival at 3, 5, and 8 years in the training and validation cohorts. A: Area under the curve of training cohort; B: Area under the curve of validation cohort; C: Calibration curve of training cohort; D: Calibration curve of validation cohort. ROC: Receiver operating characteristic; TBS: Tumor burden score; GMWG: Gamma-glutamyl transpeptidase and white blood cells; NLR: Neutrophil-to-lymphocyte ratio; BCLC: Barcelona Clinic Liver Cancer; AUC: Area under the curve.
