Serum gamma-glutamyltranspeptidase distinguishes non-alcoholic fatty liver disease at high risk.

Abstract

Multinominal logistic regression analysis showed that increased GGT level was a risk factor for advanced fibrosis in NAFLD (OR: 1.0, CI: 0.98-1.01; p =0.032). Using serum GGT levels the area under the ROC curve for the prediction of advanced fibrosis was 0.74 (95% CI: 0.54-0.94). The serum GGT cut-off value for the prediction of advanced fibrosis was 96.5 U/L; with 83% sensitivity and 69% specificity.
