Table 3. Evaluation of antioxidant levels and laboratory findings according to the control group in obese and non-obese NAFLD patients.

Statistics: one-way analysis of variance: posthoc = Scheffe alpha test.

*Independent Student’s t-test. It shows the statistical significance between non-obese NAFLD and obese NAFLD.

**It shows the statistical importance in one-way analysis of variance: posthoc = Scheffe test.

Note: Data are presented as mean ± SD

NAFLD, nonalcoholic fatty liver disease; AST, aspartate aminotransferase; ALT, alanine aminotransferase; GGT, gamma-glutamyl transferase; PTH, parathyroid hormone; TAS, total antioxidant level; TOS, total oxidant status
