Bedogni 2006 · FLI

Formula and criteria

L = 0.953 × ln(triglycerides) + 0.139 × BMI + 0.718 × ln(GGT) + 0.053 × waist circumference − 15.745; FLI = 100 × exp(L)/(1 + exp(L)). Triglycerides in mg/dL, GGT in U/L, BMI in kg/m² and waist circumference in cm.

Population and limitations

Index derived in adults. Does not diagnose steatosis or assess fibrosis. Independent clinical review has not been performed.
