aPrevalence ratios (95% confidence intervals) for rheumatoid arthritis (RA) participants and controls in the Evaluation of Subclinical Cardiovascular Disease and Predictors of Events in Rheumatoid Arthritis study. Prevalence ratios indicate the ratio of the prevalence of coronary artery calcification > 0 for RA participants compared with Multi-Ethnic Study of Atherosclerosis controls. Analyses include 1,222 subjects with complete data (RA, n = 193; control, n = 1,029). Model 1, crude model, no adjustment; model 2, adjusted for demographics (age, gender (where appropriate), race, and highest educational level attained); model 3, adjusted for model 2 covariates + cardiovascular risk factors (hypertension, high-density lipoprotein-cholesterol and low-density lipoprotein-cholesterol, diabetes, ever smoking, and use of lipid-lowering medication); model 4, adjusted for model 3 covariates + log IL-6. bAdditional covariates tested but noncontributory to the model: log CRP, log fibrinogen, log soluble intracellular adhesion molecule, triglycerides, exercise, body mass index, and waist circumference. *P value for the gender interaction significant at < 0.05.
