Journal corrects CrossFit injury data in paper at center of lawsuit

XLargeThumb.00124278-201509000-00000.CVA study on the trendy and grueling workout regimen known as CrossFit has a correction concerning the number of participants hurt during 10 weeks of training. The paper has been the center of multiple lawsuits  — one by CrossFit, and one by a CrossFit gym owner — for allegedly over-inflating the risks associated with the regimen.

The original paper claimed that 9 of 54 participants dropped out of the study due to “overuse or injury.” The correction note says that just two left for those reasons.

The paper, published in The Journal of Strength and Conditioning Research actually concludes that CrossFit has some benefits. According to the abstract: Continue reading Journal corrects CrossFit injury data in paper at center of lawsuit

Lizards aren’t getting hotter faster than the planet after all, says retraction

EcographyA paper that raised alarms by suggesting lizards were warming even faster than the planet has been retracted after the authors employed the wrong method to measure temperatures.

Some scientists thought that, because of the way lizards retain heat to regulate their cold-blooded bodies, they might be more sensitive to temperature changes. Well, not in this case. The paper has been retracted from Ecography because the scientists erred in calculating the “radiative conductance of the animal” — basically, how much heat it can get rid of — such that the “broad-scale” conclusions of the study are invalid.

The notice for the aptly named paper “Lizards could be warming faster than climate” reads: Continue reading Lizards aren’t getting hotter faster than the planet after all, says retraction

Former accounting prof adds his 32nd retraction

Another retraction makes 32.5 for former accounting professor James E. Hunton, and earns him the #10 slot on our leaderboard.

Though he resigned from his position at Bentley University in 2012, the story didn’t end there: In 2014, a university investigation found he’d committed misconduct in two papers. The, in June 2015, he notched 25 retractions all at once.

The newly retracted paper, “Effects of Anonymous Whistle- Blowing and Perceived Reputation Threats on Investigations of Whistle-Blowing Allegations by Audit Committee Members,” published in the Journal of Management Studies, suggests that, for public corporations, an anonymous whistleblower might not be as effective as an alert from a known source. The publisher Wiley put out a press release for the paper in 2010, and it succeeded in garnering some coverage.

Whether its conclusion remains valid is unclear, as Hunton didn’t provide evidence to support the validity of the data. The note explains:

Three retractions for geriatric medicine researcher

Screen Shot 2015-08-20 at 11.51.11 AMA trio of papers on health issues in elderly patients, all sharing an author, have been retracted from Geriatrics & Gerontology International. 

The reasons for the retractions range from expired kits, an “unattributed overlap” with another paper, “authorship issues,” and issues over sample sizes.

Tomader Taha Abdel Rahman, a researcher at Ain Shams University in Cairo, is the first author on two of the papers, and second author on the third.

Here’s the retraction note for a paper that showed elderly adults with chronic hepatitis C are at risk of having cognitive issues:

Authors’ pharma ties cause Cochrane to withdraw two diabetes reviews

Cochrane_LogoThe Cochrane Library has withdrawn two reviews evaluating the effectiveness of diabetes treatments because some of the papers’ authors work with pharmaceutical companies.

Bianca Hemmingsen, first author on both reviews, told us the Cochrane Library asked the authors to remove the researchers with ties to pharma, but after one “refused to withdraw,” both papers were pulled entirely.

However, Hemmingsen insists that their employment had no impact on either paper.

This breaks the typical mold for Cochrane withdrawals, which are usually only pulled to indicate updates and show that older reviews no longer represent the best evidence.

Two groups mistakenly publish case reports on the same patient

Journal of Clinical Pharmacy and Therapeutics

Talk about a popular patient: A woman who developed a case of internal bleeding while taking the anticoagulant Xarelto (rivaroxaban) was written up in not one — but two — case reports. The trouble was, both groups didn’t realize what the other was doing, so the more recent article is now being retracted from the Journal of Clinical Pharmacy and Therapeutics.

The authors, a trio of doctors at Sakarya University in Turkey, described the case of a 75 year-old woman who came to the emergency room for fatigue and stomach pain after taking rivaroxaban for three days. A scan revealed a rectus sheath hematoma.

However, the case had already been published a few months earlier in the Indian Journal of Pharmacology by a separate group of doctors from Sakarya, along with authors from Yenikent State Hospital and Vakfikebir State Hospital.

Sea squirt draft paper published by mistake

cover (1)

A paper on the evolution and development of urochordata — also known as sea squirts — was published in an under-developed form: Due to the publishers’ “error,” a “preliminary draft” of the article was published online in Developmental Dynamics last year.

The draft has been retracted; we can no longer find it on the site at all. The final copy of the paper has been posted in its place.

Here’s the retraction note in full for “Development, Metamorphosis, Morphology and Diversity: Evolution of Chordates muscles and the Origin of Vertebrates”:

Three more retractions for former record-holder Boldt, maybe more to come

m_cover

Justus Liebig University in Germany has been investigating concerns that Joachim Boldt, number two on the Retraction Watch Leaderboard and now up to 92 retractions, may have “manipulated” more data than previously believed.

Until now, the vast majority of Boldt’s retractions were thought to have involved inadequate ethics approval. However, new retraction notices for Boldt’s research suggest that there’s evidence the researcher also engaged in significant data manipulation.

The first retraction from the university investigation emerged last year. Two of three new notices cite the investigation specifically, and an informant at the university told us that there are more retractions to come.

Here are the retracted papers that are freshly on the record, starting with an August retraction for a 1991 Anesthesiology paper (cited 37 times, according to Thomson Scientific’s Web of Knowledge):

“Major overlap” forces retraction of osteoporosis paper

j adv nursThe Journal of Advanced Nursing has retracted a 2006 paper by a group of authors in Hong Kong who lifted much of the text from a previous article of theirs in a competing publication.

The article, “Osteoporosis prevention education programme for women,” came from Moon Fai Chan and C.Y. Ko in the School of Nursing at the Hong Kong Polytechnic University. Per the abstract:

To catch a cheat: Paper improves on stats method that nailed prolific retractor Fujii

anaesthesiaThe author of a 2012 paper in Anaesthesia which offered the statistical equivalent of coffin nails to the case against record-breaking fraudster Yoshitaka Fujii (currently at the top of our leaderboard) has written a new article in which he claims to have improved upon his approach.

As we’ve written previously, John Carlisle, an anesthesiologist in the United Kingdom, analyzed nearly 170 papers by Fujii and found aspects of the reported data to be astronomically improbable. It turns out, however, that he made a mistake that, while not fatal to his initial conclusions, required fixing in a follow-up paper, titled “Calculating the probability of random sampling for continuous variables in submitted or published randomised controlled trials,” also published in Anaesthesia.

According to the abstract:
