In conclusion, markers of obesity (BMI and W/H) and HCV genotype 3 are associated with the extent of steatosis and type of fatty liver. Higher grade of steatosis and presence of superimposed NASH are both associated with advanced hepatic fibrosis.

In patients with chronic hepatitis C, type 2 DM and superimposed steatohepatitis are independently associated with advanced fibrosis.
