FLI

FLI = (e0.953*loge(triglycerides) + 0.139*BMI + 0.718*loge(GGT) + 0.053*waist circumference−15.745)/(1 + e0.953*loge(triglycerides) + 0.139*BMI + 0.718*loge(GGT) + 0.053*waist circumference−15.745)*100

NAFLD LFS

NAFLD LFS =  − 2.89 + 1.18 * metabolic syndrome (yes = 1 / no = 0) + 0.45*type 2 diabetes (yes = 2 / no = 0) + 0.15 * fasting serum insulin (mU/L) + 0.04 * AST(U/L)—0.94 * AST/ALT

[18]

Liver fat (%)

10(− 0.805+0.282 * metabolic syndrome (yes = 1 / no = 0) + 0.078*type 2 diabetes (yes = 2 / no = 0) + 0.525 * lg(fs − insulin[mU/L]) + 0.521 * lg(fs − AST[U/L]) − 0.454 * lg(AST/ALT))
