Progression of atherosclerosis in asymptomatic carotid arteries after contralateral endarterectomy: A 10-year prospective study Enzo Ballotta, MD, Giuseppe Da Giau, MD, Giorgio Meneghetti, MD, Bruno Barbon, MD, Carmelo Militello, MD, Claudio Baracchini, MD Journal of Vascular Surgery Volume 45, Issue 3, Pages (March 2007) DOI: /j.jvs Copyright © 2007 The Society for Vascular Surgery Terms and Conditions

Fig 1 Kaplan-Meier curves show the probability of freedom from any progression, from progression from mild to moderate stenosis, and from progression from moderate to severe stenosis. Percentages on the right represent rates of freedom from disease progression at 10 years. The standard error is less than 10% at each time point in each curve. The range of standard errors for any progression is 0% to 3.9%, for mild to moderate stenosis is 0% to 4.2%, and for moderate to severe stenosis is 0% to 8.2%. Raw numbers of the patients at risk of disease progression analyzed in each subset at each time point are provided below the figure.

Fig 2 Kaplan-Meier curves show the probability of freedom from neurologic events for patients with 30% or greater carotid disease and for those with a moderate stenosis that progressed to a severe lesion. Percentages on the right represent rates of freedom at 10 years. The standard error is less than 10% at each time point in each curve. The range of standard errors for 30% or greater carotid disease is 0% to 2.3% and for moderate to severe stenosis is 0% to 7.8%. Raw numbers of the patients at risk analyzed in each subset at each time point are provided below the figure.
