On the 6th December 2008, in my role as Editor-in-Chief of the International Journal of Cardiology, I received an email from Professor Harold Garner of UT Southwestern Medical Center, Dallas. Professor Garner told me that using a new search engine methodology (eTBLAST) he and colleagues had identified a paper in the International Journal of Cardiology published in 1996 which had remarkable text and data similarity to an earlier paper published in 1992 in the New England Journal of Medicine. They had detected this similarity after randomly selecting citations from Medline and submitting them to the tool to find other highly similar citations as part of their NIH/R01 funded research on the ethics of publication. We have been notified that all such cases are reported in a database, Déjà Vu (http://spore.swmed.edu/dejavu/). We investigated the text of the two papers and we agreed that there was such a similarity that the later paper must have plagiarized the earlier paper, and in doing so infringed the copyright. In accordance with our previously published standards on ethical publishing in the Journal we hereby retract the paper "The prognostic value of serum troponin T in unstable angina. Gökhan Cin V, Gök H, Kaptanoǧlu B. Int J Cardiol. 1996 Mar;53(3):237-44. ".
