Depending on the presence of hepatic steatosis there were significant differences in the values of alanine aminotransferase (p=0.0006; R 0.25), glycaemia after 2 hours of OGTT (p=0.0059; R 0.20), fasting insulin (p= 0.0006; R 0.23) and all insulin resistance indices (Table 2). This evidence concerns the gene INS and fatty liver disease.
