Characteristics of nonalcoholic fatty liver disease-related models

Model	Full name	Country, year	Formula
FLI [10]	Fatty Liver Index	Italy, 2006	FLI = e 0.953 × ln TG + 0.139 × BMI + 0.718 × ln (GGT) + 0.053 × WC − 15.745)/(1 + e 0.953 × ln TG + 0.139 × BMI + 0.718 × ln (GGT) + 0.053 × WC − 15.745) × 100
FLD [14]	Fatty liver disease index	China, 2013	FLD index = BMI + TG + 3 (ALT/AST ratio) + 2HG (presence of HG, HG = 1; absence of HG, HG = 0)
ZJU [15]	Zhejiang University index	China, 2015	ZJU index = BMI + FPG + TG + 3 ALT/AST ratio + 2 (if female)
LAP [12]	Lipid accumulation product	Italy, 2010	LAP (male) = (WC – 65) × TG LAP (female) = (WC – 58) × TG
CAP [16]	Regression formula of controlled attenuation parameter	China, 2018	CAP = 113.163 + 0.252 × ALT + 6.316 × BMI
WHtR [9]	Waist-to-Height Ratio	Japan, 1995	WHtR = WC/height × 100
TyG [11]	Triglyceride and glucose index	Mexico, 2008	TyG = ln[(TG × FPG)/2]
VAI [13]	Visceral adiposity index	Italy, 2012	VAI (male) = (WC/(39.68 + (1.88 × BMI))) × (TG/1.03) × (1.31/HDL-C) VAI (female) = (WC/(39.58 + (1.89 × BMI))) × (TG/0.81) × (1.52/HDL-C)

ALT, alanine aminotransferase; AST, aspartic transaminase; BP, blood pressure; DM, diabetes mellitus; FPG, fasting plasma glucose; GGT, gamma-glutamyl transpeptidase; HG, hyperglycemia; HDL-C, high-density lipoprotein cholesterol; TG, triglyceride; TB, total bilirubin; TC, total cholesterol; WC, waist circumference; platelet count.
