ADIPOQ and rheumatoid arthritis: Likewise, serum adiponectin concentrations expressed by three ways were all significantly higher in patients with RA than those in controls [11.5 μg/mL (7.0–16.2 μg/mL) vs. 7.7 μg/mL (5.7–11.1 μg/mL), P < 0.001; 0.54 μg/mL/BMI (0.31–0.79 μg/mL/BMI) vs. 0.36 μg/mL/BMI (0.22–0.47 μg/mL/BMI), P < 0.001; 0.74 μg/mL/kg fat (0.41–1.50 μg/mL/kg fat) vs. 0.44 μg/mL/kg fat (0.27–0.77 μg/mL/kg fat), P < 0.001].
