Number of strokes prevented at 5 years by performing 1000 CEAs. Effect of gender and timing from event to CEA on prevention of late stroke relative to degree of stenosis (recalculated from CETC data and reproduced with permission from AR Naylor).⁴

Strokes prevented per 1000 CEAs at 5 years stratified for; (i) delay from last event to surgery and (ii) 30-day death/stroke risk (recalculated from CETC and reproduced with permission from AR Naylor).⁴
