Table 3 Independent predictors of steatosis grade 2–3, NASH, and of fibrosis at logistic regression analysis in 115 consecutive biopsied patients with NAFLD with available DNA and serum samples at the time of liver biopsy

From: The i148m Pnpla3 polymorphism influences serum adiponectin in patients with fatty liver and healthy controls
