ROC-curve analysis for the prediction of advanced fibrosis with NIKEI, FIB-4 index and NAFLD fibrosis score.
a) estimation group (n = 154 with complete data for calculating both indices); b) validation group (n = 86 with complete data for calculating both indices). c) NAFLD fibrosis score (n = 120).

NIKEI test performance in estimation group (EG) and validation group (VG).

Stepwise combination of FIB-4 index and NIKEI.
Algorithm for the prediction of advanced fibrosis in NAFLD patients (estimation group, n = 154 with complete data for calculating both indices). Algorithm starts with the calculation of the FIB4 index followed by calculating NIKEI only for patients with negative or indeterminate test results. Shaded rectangles: liver biopsies which could have been avoided.
