Relationship between the Framingham risk score and the probability of higher calcium scores among patients with early and long-standing rheumatoid arthritis (RA) and control subjects. The results of a multivariable model examining the association of the Framingham risk and coronary calcium scores after adjusting for disease status, age, gender, and homocysteine are depicted. Due to differences in the intercept, patients with long-standing RA (late) have a greater probability of higher coronary calcium scores than control subjects, independent of Framingham risk scores (odds ratio = 2.46, 95% confidence interval 1.20 to 5.05).
