ABSTRACT
Introduction and aim. Given that early identification of non-alcoholic fatty liver disease (NAFLD) is an important issue for primary
prevention of hepatic disease, the objectives of this study were to evaluate the efficacy of the product of triglyceride and glucose
levels (TyG) for screening simple steatosis and non-alcoholic steatohepatitis (NASH) in asymptomatic women, and to compare its
efficacy
vs. other biomarkers for recognizing NAFLD.
Material and methods. Asymptomatic women aged 20 to 65 years were
enrolled into a cross-sectional study. The optimal values of TyG, for screening simple steatosis and NASH were established on a
Receiver Operating Characteristic scatter plot; the sensitivity, specificity, and likelihood ratios of TyG index were estimated versus
liver biopsy. According sensitivity and specificity, the efficacy of TyG was compared versus the well-known clinical biomarkers for
recognizing NAFLD.
Results. A total of 50 asymptomatic women were enrolled. The best cutoff point of TyG for screening simple
steatosis was 4.58 (sensitivity 0.94, specificity 0.69); in addition, the best cutoff point of TyG index for screening NASH was 4.59
(sensitivity 0.87, specificity 0.69). The positive and negative likelihood ratios were 3.03 and 0.08 for simple steatosis, and 2.80 and
0.18 for NASH. As compared versus SteatoTest, NashTest, Fatty liver index, and Algorithm, the TyG showed to be the best test
for screening.
Conclusions. TyG has high sensitivity and low negative likelihood ratio; as compared with other clinical biomarkers,
the TyG showed to be the best test for screening simple steatosis and NASH.
