Editorial summary: This article was published by authors from the University of Pharmacy and Medicine in Targu-Mures, Romania, which include the current Rector of the University,  Prof Leonard Azamfirei, in the Romanian journal Acta Medica Marisiensis, vol 57, no 5, 2011, pp 460-462.

Large amounts of copy-paste plagiarism were identified by several reviewers. Strikingly, some statistical data and also numerical results are identical to the ones found in the original paper published 4 years earlier by the authors Stachon et al. Until this date, these numerical data have not been verified as true. Identical reproduction of numerical data falls under data fabrication and duplication.

Prof Leonard Azamfirei is now the Rector of the University of Pharmacy and Medicine in Targu-Mures, Romania. He was formerly the Vice-Dean for Scientific Research of the same university . . .
