Carotid revascularization measured within 90 days after acute ischemic stroke. Carotid imaging included ultrasound, magnetic resonance angiography, or computerized tomography angiography. Cardiac monitoring included cardiac event monitor or implantable loop recorder. Echocardiogram include transthoracic and transesophageal echocardiogram. Logistic regression models estimated the odds of receiving the individual procedures (secondary outcomes) before and after adjusting for patient and hospital factors.

Adjusted models included patient factors (age, sex, race/ethnicity, education, net wealth, income, Charlson comorbidity index score, depressive symptoms, functional limitations in basic and instrumental activities of daily living, marital status/living arrangement, geographic proximity to adult children, and having an adult daughter) and hospital factors (medical school affiliate or teaching hospital, region, bed size, and authority type).

We do not present adjusted results for these individual procedures because numbers are small.
