FGF21 and steatosis: The results indicated that stepwise increments in BMI (B = 0.174, P = 0.033), γ-GT (B = 0.368, P < 0.001), TG (B = 0.180, P = 0.035), and log-transformed FGF-21 levels (B = 0.273, P = 0.002) were significantly correlated the steatosis grade of obese and overweight children (P < 0.05) (Table 2).
