Diagnostic performance of the NAFLD score.

<p>Cut-off values and the classification of patients on the basis of the NAFLD fibrosis score (n = 120). A patient with a value below the lower cut-off level was classified as healthy (no advanced fibrosis), with a value above the upper cut-off level as morbid (advanced fibrosis). Patients with values between the cut-off levels are intermediate/not classifiable.
