Adjusted mean Agatston calcium scores for participants with any coronary artery calcification according to rheumatoid arthritis (RA) status and (a) gender and (b) age category. Analyses include 667 subjects with complete data. Analyses were adjusted for age, gender (where appropriate), race, hypertension, high-density lipoprotein-cholesterol and low-density lipoprotein-cholesterol, diabetes, ever smoking, and use of lipid-lowering medication.
