TNF-α correlated significantly with hepatic steatosis (r = 0.415, P < 0.05), lobular inflammation (r = 0.441, P < 0.05), ballooning (r = 0.557, P < 0.01), steatohepatitis (r = 0.466, P < 0.05) and fibrosis septa around the central vein (r = 0.487, P < 0.05). This evidence concerns the gene TNF and Hepatic steatosis.
