MS paper second to fall following University of Queensland investigation
no primary data can be located, and no evidence has been found that the study described in the article was conducted.
UQ subsequently examined 92 papers published since 2007 by former staff members Bruce Murdoch and Caroline Barwood.
The examination did not reveal any other instances of research not supported by primary data or of research undertaken without ethics approval.
It did raise concerns about statistical methodology in the Aphasiology paper, and about the attribution of authorship of a small number of papers.
UQ provided details of those concerns to the editors of the journals to enable them to make informed decisions on what action, if any, they would take.
Professor Murdoch was also on the editorial board of the journal Aphasiology for more than two decades before he stepped aside several months ago.
The ABC understands the latest retraction is not due to intentionally fabricated research data, and instead a statistical error is to blame.
Here’s the notice:
The following article has been retracted from publication in the Taylor & Francis journal Aphasiology:
Barwood, C.H.S., & Murdoch B.E. Cognitive linguistic deficits in relapsing-remitting multiple sclerosis. Aphasiology, 27: 1459–1471. http://dx.doi.org/10.1080/02687038.2013.808315. Version of Record published online 27 June 2013.
The article has been retracted with the authority of the University of Queensland and the journal Editor in Chief, Professor Chris Code, and Taylor & Francis.
The retraction is due to the findings of an investigation by the University of Queensland, which has established that: the manuscript claims to have a control group of 15, however only 7 control participants were documented and some control data were re-used to enlarge the control group. This lack of independence within control data is not acknowledged in the manuscript.
The paper has yet to be cited, according to Thomson Scientific’s Web of Knowledge.
