On page 4035 in the 26 June 2014 issue, reference to financial support from the Deutsche José Carreras Leukämie-Stiftung was omitted. The Acknowledgments should have read: “We thank Axel Benner (German Cancer Research Center, Heidelberg, Germany) for his statistical review and Daniela Späth (Department of Internal Medicine III, University Hospital Ulm, Ulm, Germany) for her support in the clinical trials office. This work was supported by a grant from the Deutsche José Carreras Leukämie-Stiftung (DJCLS R 06/32).” The error has been corrected in the online version, which now differs from the print version.
