The primary composite clinical outcome consisted of stroke or TIA located in any vascular territory, occurring between the post-treatment MRI scan and the end of available follow-up. Stroke was defined as a rapidly developing clinical syndrome of focal disturbance of cerebral function lasting >24 hours or leading to death with no apparent cause other than that of vascular origin. TIA was defined as a rapidly developing clinical syndrome of focal disturbance of cerebral function lasting <24 hour with no apparent cause other than cerebral ischemia. Secondary outcomes were ipsilateral stroke/TIA, any stroke, and ipsilateral stroke.
