Diagnostic efficacy and influencing factors of non-invasive liver fibrosis scores in chronic hepatitis B fibrosis: Cross-sectional study

Figure 3 Receiver operating characteristic curves of different fibrosis assessment indicators. A: Receiver operating characteristic (ROC) curves for comparing any fibrosis (F1-F4) vs no fibrosis (F0); B: ROC curves for comparing significant fibrosis (F3-F4) vs no or mild fibrosis (F0-F2). The curves correspond to different liver fibrosis assessment indicators: Aspartate transaminase to platelet ratio index, gamma-glutamyl transferase to platelet ratio, fibrosis-4 index, and the aspartate aminotransferase to alanine aminotransferase ratio. The values in the figure represent the area under the curve for each non-invasive liver fibrosis indicator. APRI: Aspartate aminotransferase to platelet ratio index; GPR: Gamma-glutamyl transferase to platelet ratio; FIB-4: Fibrosis-4 index; AST/ALT: Aspartate aminotransferase to alanine aminotransferase ratio; ROC: Receiver operating characteristic.
