Sex difference in the effect of time from symptoms to surgery on benefit from carotid endarterectomy for TIA and nondisabling stroke
Pooled data from the NASCET and the ECST showing the absolute reduction with surgery in the five-year risk of each of the three main trial outcomes (ie, time to first ipsilateral ischemic stroke and any perioperative stroke or death) in patients with 50 to 69% carotid artery stenosis (light bars) and ≥70% carotid artery stenosis without near-occlusion (dark bars), stratified by the time from last symptomatic event to randomization and sex. The numbers adjacent to the bars indicate the exact absolute risk reduction (ARR).
