To explore the potential relationship between Fetuin B and obesity, 215 subjects were divided into three groups according to the serum Fetuin B tertiles, with concentrations (mean ± SD) as follows: Tertile 1, 2.752 ± 0.626 μg/mL; Tertile 2, 4.260 ± 0.358 μg/mL; Tertile 3, 5.721 ± 0.733 μg/mL. The gene discussed is FETUB; the disease is Obesity.
