However, RA patients with hypouricemia showed higher levels of HDL-C (mean 1.50 mmol/L vs. 1.39 mmol/L), lower levels of TG (mean 0.98 mmol/L vs. 1.16 mmol/L), BMI (mean 21.1 kg/m2 vs. 21.9 kg/m2), and serum albumin (mean 33.3 g/L vs. 34.8 g/L, all P < 0.05). This evidence concerns the gene ALB and rheumatoid arthritis.
