Relative and absolute odds of an arterial thromboembolic event during 30-day intervals in the 360 days before cancer diagnosis. The comparator group for the relative odds calculation was control patients without cancer who were individually matched to cancer cases by age, sex, race, geographic region, Charlson comorbidity index, history of hypertension, and history of atrial fibrillation. Arterial thromboembolic events were defined as a composite of myocardial infarction and ischemic stroke. Dashed blue lines, 95% CIs for the relative odds of arterial thromboembolic events.
