Restenosis and risk of stroke after stenting or endarterectomy for symptomatic carotid stenosis in the International Carotid Stenting Study (ICSS): secondary analysis of a randomised trial

  Figure 2. Cumulative incidence of (A) at least moderate (≥50%) carotid artery restenosis or occlusion and (B) severe (≥70%) carotid artery restenosis or occlusion after completed treatment Cumulative incidence was estimated by life-table analysis. Plots stop at 7 years' follow-up because the number of patients at risk beyond that time was fewer than 100, but analyses were based on all follow-up data (maximum 10 years). HR=unadjusted hazard ratio.
