Moreover, the logarithmically transformed FGF-21 levels were positively and significantly correlated with liver steatosis grade (B = 0.516, P < 0.001) whereas logarithmically transformed adiponectin (B = −0.217, P = 0.067) and leptin levels (B = 0.003, P = 0.978) were not. The gene discussed is FGF21; the disease is Hepatic steatosis.
