On February 9, 2006, we published an Expression of Concern1 about two articles we had published by Jon Sudb? et al.2,3 In the Expression of Concern, we indicated that we were awaiting the results of an investigation by Dr. Sudb?'s institution. That investigation was undertaken by a commission appointed by the Rikshospitalet–Radiumhospitalet Medical Center and the University of Oslo. The commission's report was filed on June 30, 2006, in Norwegian (http://www.rikshospitalet.no/content/res_bibl/6621.pdf), and we received an official English translation on September 1, 2006 (see the Supplementary Appendix, available with the full text of this article at www.nejm.org).
In early September, we sent copies of the translated report to all the authors of the two Journal articles by Jon Sudb? et al. We asked each author to respond before September 30, 2006. We have now received responses from all authors except Asle Sudb?. Each of the responding authors, except Jon Sudb?, has indicated that the data that form the foundation for the articles have been called into question by the findings of the commission, and each of them has requested that the articles be retracted. Jon Sudb? alone does not agree with the commission's report. Given the weight of evidence offered in the commission's report and the requests of most of the authors of the articles, we retract both articles.
