Ensemble for evaluating diagnostic efficacy of non-invasive indices in predicting liver fibrosis in untreated hepatitis C virus population

Figure 1 Correlation plots for special investigations vs liver stiffness measurement. A: Serum fibronectin vs liver stiffness measurement (LSM); B: Alanine aminotransferase ratio (AAR) vs LSM; C: Aspartate aminotransferase to platelet ratio index (APRI) vs LSM; D: Fibrosis-4 (FIB-4) vs LSM. ALT: Alanine aminotransferase; AST: Aspartate aminotransferase.

Figure 2 Receiver operating characteristic curves. A: Fibrosis; B: Severe fibrosis; C: Moderate fibrosis; D: Mild fibrosis. S. Fibronectin: Serum fibronectin.
