Conversely, visceral obesity (OR=3.653, 95%CI=2.984-4.471, P<0.001), hypertension (OR=1.654, 95%CI=1.290-2.121, P<0.001), hypertriglyceridemia (OR=3.455, 95%CI=2.784-4.288, P<0.001), Low HDL-C (OR=1.879, 95%CI=1.536-2.299, P<0.001) and ALT > 40U/L (OR=2.729, 95%CI=2.060-3.615, P<0.001) were independent risk factors of NAFLD (Table 4). This evidence concerns the gene GPT and hypertriglyceridemia.
