Figure 8 Comparative assessment of diagnostic performance between Logistic Regression model and conventional biomarkers using receiver operating characteristic analysis. A: Receiver operating characteristic (ROC) curve evaluation in the training cohort; B: Validation set ROC curve analysis; C: Test set ROC curve evaluation. ROC: Receiver operating characteristic; AUC: Area under the curve; AFP: Alpha-fetoprotein; MELD: Model for End-Stage Liver Disease.
