Multivariable ischemic stroke risk (odds ratios and 95% confidence intervals on log scale) associated with rheumatoid arthritis (RA) treatment in a 6-month window before the index stroke, adjusted for Health Assessment Questionnaire score, total joint replacement, RA duration, and for low-dose aspirin and comorbidity index immediately prior to index observation. Numbers in parentheses represent the number of patients using that therapy (cases and controls). Analysis included 41 RA patients with ischemic stroke and 791 RA patients without ischemic stroke. Anti-TNF = anti–tumor necrosis factor.
