Fig. 4. Receiver operating characteristic curves of coefficient of variation used for diagnosis in patient with significant fibrosis (aspartate aminotransferase-to-platelet ratio > 0.5 and FIB-4 score > 1.45).

AUC was 0.875 in APRI version with optimal cut-off values of 4.1866 (red line). AUC was 0.831 in FIB-4 version with optimal cut-off values of 4.5642 (blue line). APRI = aspartate aminotransferase to platelet ratio index, AUC = area under the curve, FIB-4 = fibrosis-4
