The exam took place several months after his university found he had allowed a breach of research integrity in his lab and a month before news of the investigation and his departure from the school made national news in Canada.

On Dec. 5, Cory Toth, a former professor at the University of Calgary (U of C), appeared in an Edmonton, Alberta courtroom as the plaintiff in a lawsuit filed in Provincial Civil Court. The story was first reported by the Edmonton Journal.

Court documents, which we’ve made available here, show that in April 2016 Toth sued Western Medical Assessments (WMA) — the company that hired him to perform the exam, which was used in another case — and Michele Reeves — the lawyer who hired WMA.

Pain study retracted for bogus data is second withdrawal for University of Calgary group

with 10 comments

molpainBack in January 2013, we wrote about the retraction of a paper in Diabetes that the authors had “submitted without knowledge of inherent errors or abnormalities that they recognized in retrospect after submission.”

Now, Molecular Pain has retracted a paper by the same authors, this time for data manipulation. The article, “Comparison of central versus peripheral delivery of pregabalin in neuropathic pain states,” was written by Cory Toth, a clinical neuroscientist at the University of Calgary, in Canada, and colleagues. It has been cited eight times, according to Thomson Scientific’s Web of Knowledge.

Toth said of the Diabetes article at the time:
