The accuracy of predicting the fibrosis stage was determined by receiver operating characteristic curve analysis in patients with FALD.

The AUC for the platelet count, FIB-4 index, and full-length CTGF was 0.744, 0.567, and 0.822, respectively. Full-length CTGF was the best predictor of fibrosis in patients with FALD. AUC, area under the curve; CTGF, connective tissue growth factor; FALD, Fontan-associated liver disease; FIB-4, fibrosis-4.
