*3.4.2 Fatty liver index (FLI)*

The FLI was calculated based on a mathematical formula that included measurements of waist circumference (cm), BMI (kg/m2 ), gamma-glutamyl-transpeptidase (GGT) (U/l), and triglycerides (mg/dl), as follows: FLI = (e 0.953\*log e (triglycerides) + 0.139\*BMI + 0.718\*log e (GGT) + 0.053\*waist circumference – 15.745)/(1 + e 0.953\*log e (triglycerides) + 0.139\*BMI + 0.718\*log e (GGT) + 0.053\*waist circumference – 15.745) × 100. The values could range between 0 and 100. If the FLI is under 30, there is a very low probability of fatty liver (FL), but an FLI over 60 substantially magnifies the risk for FL, prompting complementary examinations [24].
