I found a retracted medical study that is cited by the bloodless/blood management world.
I wonder when they will get around to recognizing the retraction in the blood management world. This study is still being used as a reference - the latest study that cited it was published in 2016.
NOTICE OF RETRACTION The following article from Anaesthesia, ‘Safety of cardiac surgery without blood transfusion: a retrospective study in Jehovah’s Witness patients’, by El Azab SR, Vrakking R, Verhage [sic] G and Rosseel PMJ, published online in Wiley Online Library (http://onlinelibrary.wiley.com/doi/10.1111/j.1365-2044.2009.06232.x/full) on 17 March 2010 and in Volume 65, Number 4, pages 348-52, has been retracted by agreement between three of the named authors (R Vrakking, G Verhaegh and PMJ Rosseel), the Journal Editor-in-Chief, Steve Yentis, and Blackwell Publishing Ltd. The retraction has been agreed following confirmation by the Amphia Hospital Ethics Committee that the study did not have ethical approval as claimed. In addition, the article was written and submitted without the knowledge or consent of R Vrakking, G Verhaegh and PMJ Rosseel. It has not been possible to obtain a response from the corresponding author SR El Azab.
I posted this study to a website I follow - http://retractionwatch.com/
I am hoping it will come up on their radar and get mentioned by their writing and investigative staff.
