Differences between men and women were statistically significant except for age and total cholesterol (P < 0.05 by t test). BMI: Body mass index; BP: Blood pressure; AST: Aspartate transferase; ALT: Alanine transferase; GGT: Gamma-glutamyl transferase; HDL: High-density lipoprotein; LDL: Low-density lipoprotein; CRP: C-reactive protein; TSH: Thyroid stimulating hormone.
