The first 30 days after a procedure, and patients with restenosis in the first 30 days, are excluded from this analysis. Patients were censored at the time of stroke or at any ipsilateral procedure during follow-up. HR=hazard ratio.

^*Adjusted for predictors of restenosis (appendix). Only participants with complete information on these baseline risk factors were included in the adjusted comparisons.
