*Posterior probability that the primary safety endpoint event rate is <15%.
†Primary safety endpoint defined as rate of death or major stroke within 30 days or neurologic death or major ipsilateral stroke within 12 months.
‡One subject fell and had a major ipsilateral stroke (subdural hematoma) at day 235 postoperatively with subsequent neurological death 1 day later and is listed under both stroke and death 31–425 days for this event.
