  • Values expressed as mean (SD) and median [IQR] for non-normally distributed data. Comparisons between rheumatoid patients and healthy controls were performed using the independent t-test. Categorical variables were compared using Fisher's exact χ2 test. Comparisons for non-parametric measurements were performed using Mann-Whitney test.

  • BMI, body mass index; CRP, C reactive protein; HDL, high-density lipoprotein; LDL, low-density lipoprotein.
