Age, hypertension, diabetes (for proximal and any CAA only), hypercholesterolemia, smoking (for distal and any CAA only), renal insufficiency
LV hypertrophy, aortic valve calcium, left atrial enlargement
Inclusion of aortic valve calcium and left atrial enlargement in the model did not meaningfully influence the magnitude of the odds ratio
No atrial fibrillation, ipsilateral large-artery stenosis ≥50%, definite cardiac source of embolism, or hypercoagulable state
