Figure 2 1-Year Results of the SAPPHIRE Trial
Major adverse events were defined as a composite of death, stroke, or myocardial infarction within 30 days, or death or ipsilateral stroke between 31 days and 1 year. In the intention-to-treat analysis (A), the rate of event-free survival at 1 year was 87.8% among patients randomly assigned to carotid stenting, compared with 79.9% among those randomly assigned to endarterectomy (p = 0.053). In the actual-treatment analysis (B), the rate of event-free survival at 1 year was 88.0% among patients who received a stent, compared with 79.9% among those who underwent endarterectomy (p = 0.048). I bars represent 1.5 times the standard error. Reproduced with permission from Yadav et al. (35).
