Correction ========== In the article by Aboyans et al, “Measurement and Interpretation of the Ankle-Brachial Index: A Scientific Statement From the American Heart Association,” which published ahead of print on November 16, 2012, and appeared in the December 11, 2012, issue of the journal (*Circulation*. 2012;126:[2890–2909](http://circ.ahajournals.org/lookup/volpage/126/2890)), a correction was needed. In the author list on page 2890, the degree listing for Dr. Pande read, “Reena L. Pande MD, PhD, FAHA.” It has been changed to read, “Reena L. Pande MD, MSc.” This correction has been made to the print version and to the current online version of the article, which is available at [http://circ.ahajournals.org/content/126/24/2890](http://circ.ahajournals.org/content/126/24/2890). * © 2013 American Heart Association, Inc.
