  1. Data presented as β and P values or odds ratio (95% confidence interval). CRP, C reactive protein; CVD, cardiovascular disease; DAS28, Disease Activity Score in 28 joints; ESR, erythrocyte sedimentation rate; HAQ, Health Assessment Questionnaire; HDL, high density lipoprotein; n/a, not available; RF, rheumatoid factor; SEVR, subendocardial viability ratio; TC, total cholesterol. *P < 0.001. Bold data represent statistically significant results.
