A: Fatty liver index (FLI) of non-alcoholic fatty liver disease (NAFLD) and non-NAFLD groups in the population with a body mass index (BMI) < 23 kg/m²; B: FLI of non-NAFLD and NAFLD groups in the population with a BMI ≥ 23 kg/m² but < 25 kg/m²; C: FLI of non-NAFLD and NAFLD groups in the population with a BMI ≥ 25 kg/m²; D: FLI of non-NAFLD and NAFLD groups in the population with a BMI < 23 kg/m² with a normal waist circumference; E: FLI of non-NAFLD and NAFLD groups in the population with a BMI ≥ 25 kg/m² with a large waist circumference. FLI: Fatty liver index; BMI: Body mass index; NAFLD: Non-alcoholic fatty liver disease.
