The odds of stroke for CAS versus CEA ranged from an adjusted odds ratio (aOR) of 1.55 (95% CI 1.36 to 1.77) to an odds ratio (OR) of 2.6 (95% CI 1.9-3.8) for immediate events, while MI was more common after CEA (28 events) than CAS (14 events) in one study (HR 0.50; 95% CI 0.26–0.94; P=0.032 for CAS).
