Figure 3. ROC Curve for LS, APRI, FIB-4, AST/ALT, FibroQ, NAFLD Fiibrosis Score, and Fiibrosis Score by Gutkowski for Fiibrosis Stage F1 - 3 Versus F4 in AIH Patients.

ROC curves for TE, FIB-4, AST/ALT, Fibro Q, and NAFLD fiibrosis score exhibit acceptable overall performance to discriminate F1 - 3 from F4, with FibroQ achieving the highest discriminatory performance. Diagonal segments are produced by ties. Areas under the curve are presented in Table 2.
