ROC curves for the diagnosis of liver inflammation (≥G1) via five indices. The AUCs of the inflammation diagnostic indices were ranked in the following order: PIIINP (0.793) > CIV (0.787) > FibroTest index (0.753) > LN (0.715) > HA (0.631), and the boundary values that were estimated by the ROC curves to indicate liver inflammation were 5.65 ng/ml, 36.2 ng/ml, –0.28, 88.65 ng/ml, and 43.5 ng/ml, respectively.
