Teresa A. Crutchley, MD, Jeffrey D. Pearce, MD, Timothy E. Craven, MSPH, Jeanette M. Stafford, MSPH, Matthew S. Edwards, MD, Kimberley J. Hansen, MD  Journal of Vascular Surgery  Volume 49, Issue 1, Pages e3 (January 2009) DOI: /j.jvs Copyright © 2009 The Society for Vascular Surgery Terms and Conditions

2 Fig 1 Long-term postoperative survival by preoperative resistive index (RI) groups with RI <0.8 vs RI ≥0.8. P value for significance of RI from multivariable model including history of coronary artery disease, history of peripheral vascular disease, change in number of blood pressure medications, and blood pressure response.

3 Fig 2 Long-term postoperative survival by preoperative resistive index (RI) groups with RI <0.8 vs RI ≥0.8 and intervention (percutaneous or open repair). Broken curves indicate point at which survival estimate standard error exceeds 10%.
