DM2, diabetes mellitus type 2; RA, rheumatoid arthritis.
Model I, crude associations.
Model II, corrected for age and gender.
Model III, corrected for cardiovascular risk factors (age and gender, systolic blood pressure, antihypertensive agents, total cholesterol/high-density lipoprotein cholesterol (TC/HDL) ratio, lipid-lowering drugs, waist circumference, creatinine and smoking).
