*The definition of the above risk models for NAFLD.
Park’s index for NAFLD: index ≥3, in which Park’s index = (ALT/AST ratio >1.5)×1+(γ-glutamyl-transferase >50)×1+(triglycerides >150)×1+(23≤ BMI <25)×2+(25≤ BMI)×3.
Hepatic steatosis index (HSI): HSI >36 for high-risk and <30 for no NAFLD, in which HSI = 8×ALT/AST ratio+BMI (+2, if diabetes;+2, if female).
Fatty liver index (FLI): FLI ≥60 for high-risk and <30 for no NAFLD, in which FLI = 1/(1+exp(−x))×100, where x = 0.953×loge (triglycerides)+0.139×BMI+0.718×loge (γ-glutamyl-transferase)+0.053×WC −15.745.
NAFLD liver fat score: score ≥−0.640, in which NAFLD liver fat score = −2.89+1.18×metabolic syndrome+0.45×diabetes+0.15×fasting insulin+0.04×AST+0.94×AST/ALT ratio.
†After imputing the missing data for alcohol consumption and menopausal status.
‡After imputing the missing data of fasting insulin levels.
