Comparison of median values of relative <i>NGF</i> and <i>p75</i>^<i>NTR</i> gene expression with serum levels of liver enzymes in individuals with and without HBV and HCV, with different degrees of the disease.

ALT: alanine aminotransferase (normal: 14 to 55 UI/L); GGT: gamma-glutamyl transferase (normal: < 50 UI/L); aNGF (normal vs. high ALT); bNGF (normal vs. high GGT); c p75NTR (normal vs. high ALT); d p75NTR (normal vs. high GGT). Comparison of median values of relative NGF and p75NTR gene expression with serum levels of liver enzymes in individuals with and without HBV and HCV, with different degrees of the disease.
