Figure 1.
Hepatic steatosis in the four BMI groups (group 1: BMI 18.5–24.9 kg/m2, group 2: 25.0–29.9 kg/m2, group 3: 30.0–39.9 kg/m2 and group 4: ≥40 kg/m2) was determined with H&E staining. Steatosis was evaluated semi-quantitatively described by Kleiner et al. [7]. No steatosis: 0–5% of parenchymal involvement by steatosis, first degree steatosis: 5–33% of parenchymal involvement by steatosis, second degree steatosis: 33–66% of parenchymal involvement by steatosis, and third degree steatosis: >66% of parenchymal involvement by steatosis.
