Patient Subgroups That Have a Stroke‐Risk Reduction Benefit With CEA Over BMT Alone Based on Historical Randomized Clinical Trials. ⁵ , ⁶ , ⁷ , ⁸ , ⁹

1	Symptomatic women with 70%–99% carotid stenosis undergoing surgery within 2–3  weeks of their same‐sided neurologic event with a 3–5‐year life expectancy
2	Symptomatic men with 70%–99% carotid stenosis undergoing surgery within 3 months of an ipsilateral neurologic event with a 3–5‐year life expectancy
3	Symptomatic men with 50%–69% carotid stenosis undergoing surgery within 2–3 wks of their same sided neurologic event with a 3–5‐year life expectancy
4	Asymptomatic men with 60%–99% stenosis aged 75–80 years with a 5‐year life expectancy who were free of any major life‐threatening condition

BMT indicates best medical therapy; and CEA, carotid endarterectomy.
