Bold values are statistically significant, p < 0.05. Values were calculated using Pearson's correlation coefficient. BMI, body mass index; DD, disease duration; ESR, erythrocyte sedimentation rate; CRP, C-reactive protein; DAS-28, disease activity score in 28 joints count; TNF-α, tumor necrosis factor-a; IL-6, interleukin-6; IL-1, interleukin-1; CIMT, carotid intima media thickness; EPCs, endothelial progenitor cells; TC, total cholesterol; HDL, high-density lipoprotein; LDL, low-density lipoprotein; TG, triglycerides.
