  1. IQR inter-quartile range, SD standard deviation, bDMARDs and sDMARDs biologic and synthetic disease-modifying antirheumatic drugs, DAS28 disease activity score using 28 joint count, CRP C-reactive protein, ESR erythrocyte sedimentation rate, HDL-c high-density lipoprotein cholesterol, sBP and dBP systolic and diastolic blood pressure. Baseline characteristics describing demographic data, rheumatoid arthritis-related disease characteristics, and cardiovascular risk factors in rheumatoid arthritis at baseline. Data are also specified on patients who do and do not experience CVD events during follow-up. In subanalyses 1, only European rheumatoid arthritis cohorts were included. In subanalyses 2, rheumatoid arthritis patients on lipid-lowering therapy and/or antihypertensive treatment were included. In subanalyses 3, analyses were performed on patients from European rheumatoid arthritis cohorts also including patients on lipid-lowering therapy and/or antihypertensive treatment
