Validation of aspartate aminotransferase to platelet ratio for diagnosis of liver fibrosis and prediction of postoperative prognosis in infants with biliary atresia

Figure 2 Receiver-operating characteristics curve for aminotransferase to platelet ratio index in the diagnosis of significant liver fibrosis or cirrhosis in biliary atresia. A: Receiver-operating characteristics (ROC) curve of F0-F1 vs F2-F4. The area under the ROC curve (AUC) of APRI for diagnosing significant fibrosis (≥ F2) was 0.75 (95%CI: 0.64-0.86, P < 0.001); B: ROC curve of F0-F3 vs F4. The area under the ROC curve (AUC) of APRI for diagnosing liver cirrhosis (= F4) was 0.81 (95%CI: 0.67-0.96, P = 0.001).
