KRT18 and steatosis: Serum resistin level in NAFLD patients had a positive correlation with WHR (r = 0.41, P = 0.001), ALT (r = 0.31, P = 0.02), GGT (r = 0.35, P = 0.007), TG (r = 0.34, P = 0.01), CK-18 fragment level (r = 0.64, P = 0.02) and histological grade of steatosis (rho = 0.43, P = 0.001) (Figure 1B).
