To the Editor We read with great interest the study investigating the association between fluoroquinolone and the short-term risk of development of aortic aneurysm by Newton et al.1 This cohort study demonstrated that fluoroquinolones were associated with a higher incidence of aortic aneurysm than alternative antibiotics. Overall, it is a well-designed study; however, we have some serious concerns about the findings of this article.
