Key clinical point: Patients with migraine are at a greater risk of experiencing rheumatoid arthritis (RA) attacks, with the risk being prominently higher among those having migraine without aura.
Major finding: The risk for RA was 1.94 times higher in patients with migraine vs control individuals (adjusted odds ratio [aOR] 1.94; 95% CI 1.74-2.17), with the risk being prominent in those with migraine without aura (aOR 1.49; 95% CI 1.35-1.64).
Study details: The data come from a meta-analysis of five studies including 321,877 participants.
