Fig 7. Receiver operating characteristic (ROC) analysis of sensitivity and specificity by proposed seven candidate biomarkers and AFP in predicting disease-free survival (DFS).

The score performance was assessed by calculating the area under the ROC (AUROC) which was 0.861 (KM method) and 0.854 (NNE method), respectively for proposed candidate biomarkers while for AFP; AUROC was 0.354 (KM method) and 0.5 (NNE method) respectively.
