In the editorial by Olson and Somers, “Treating Central Sleep Apnea in Heart Failure,” which appeared in the June 26, 2007, issue of the journal (Circulation. 2007;115:3140—3142), the following correction should be made. On page 3140, the figure “35%” in the last paragraph should be changed to “40%”. This error has been corrected in the current online version of the article.
