Why — even after reforms for an episode involving bad statistics — is it so difficult to correct the sports medicine literature? Part 1

Matthew Tenan

Two years ago, following heated debate, a sports science journal banned a statistical method from its pages, and a different journal — which had published a defense of that method earlier — decided to boost its statistical chops. But as Matthew Tenan, a data scientist with a PhD in neuroscience relates in this three-part series, that doesn’t seem to have made it any easier to correct the scientific record. Here’s part one.

In‌ ‌July‌ ‌2019,‌ ‌my‌ ‌colleague‌ ‌‌Andrew‌ ‌Vigotsky‌‌ ‌contacted‌ ‌me.‌ ‌He‌ ‌was‌ ‌curious,‌ ‌he‌ ‌said,‌ ‌whether‌ ‌a‌ paper‌ ‌published‌ ‌in‌ ‌Sports‌ ‌Medicine‌ ‌had‌ ‌undergone‌ ‌statistical‌ ‌review ‌ ‌because‌ ‌he‌ ‌was‌ concerned‌ ‌about‌ ‌some‌ ‌of‌ ‌its‌ ‌claims.‌ ‌The‌ ‌link‌ ‌he‌ ‌sent‌ ‌me‌ ‌was‌ ‌to‌ ‌“‌A‌ ‌Method‌ ‌to‌ ‌Stop‌ ‌Analyzing‌ Random‌ ‌Error‌ ‌and‌ ‌Start‌ ‌Analyzing‌ ‌Differential‌ ‌Responders‌ ‌to‌ ‌Exercise‌,”‌ ‌a‌ ‌paper‌ ‌published‌ ‌on‌ June‌ ‌28,‌ ‌2019‌ ‌by‌ ‌‌Scott‌ ‌Dankel‌‌ ‌and‌ ‌‌Jeremy‌ ‌Loenneke‌.‌

As‌ ‌it‌ ‌happened,‌ ‌I‌ ‌knew‌ ‌that‌ ‌paper,‌ ‌and‌ ‌I‌ ‌had‌ ‌also‌ ‌expressed‌ ‌concerns‌ ‌about‌ ‌it‌ ‌–‌ ‌when‌ ‌I reviewed‌ ‌it‌ ‌before‌ ‌publication‌ ‌as‌ ‌one‌ ‌of‌ ‌the‌ ‌members‌ ‌of‌ ‌the‌ ‌journal’s‌ ‌editorial‌ ‌board.‌ ‌Indeed,‌ ‌I was‌ ‌brought‌ ‌on‌ ‌to‌ ‌the‌ ‌editorial‌ ‌board‌ ‌of‌ ‌‌Sports‌ ‌Medicine‌‌ ‌because‌ ‌the‌ ‌journal‌ ‌had‌ ‌recently‌ received‌ ‌a‌ ‌lot‌ ‌of‌ ‌bad‌ ‌press‌ ‌for‌ ‌publishing‌ ‌a‌ ‌paper‌ ‌about‌ ‌another‌ ‌“novel‌ ‌statistical‌ ‌method”‌ ‌with‌ significant‌ ‌issues and I had been a vocal critic of the sports medicine and sport science‌ field developing their own statistical methods that are not used outside of the field and validated by the wider statistics community.‌ ‌

Investigation at Japanese university leads to four retractions

A group of pharmacology researchers in Japan have now lost four papers over concerns about the validity of their data.  

The studies come from a group at Kobe Gakuin University, which conducted a misconduct investigation into the articles last year and concluded that 10 papers were affected. (Note: The report is in Japanese and does not identify the person or persons responsible for the deception.)

Among the latest to be retracted is a 2012 article in the Journal of Natural Medicines titled “Honokiol suppresses the development of post-ischemic glucose intolerance and neuronal damage in mice.”

Fake peer review, made-up author take down a paper

Manipulated peer review strikes again, this time with a 2015 article whose authors appear to have created a straw mathematician to make their work seem more legit. 

The paper, “Fixed point theorems and explicit estimates for convergence rates of continuous time Markov chains,” appeared in Fixed Point Theory and Applications, a Springer Nature title. 

Its authors, purportedly, were affiliated with institutions in China and Japan. According to the acknowledgements for the article:

Heavily criticized paper blaming the sun for global warming is retracted

A controversial paper claiming that fluctuations in the sun’s magnetic field could be driving global warming has been retracted — prompting protests from most of the authors, who called the move 

a shameful step to cover up the truthful facts about the solar and Earth orbital motion reported by the retracted paper, in our replies to the reviewer comments and in the further papers.

The 2019 article, “Oscillations of the baseline of solar magnetic field and solar irradiance on a millennial timescale,” appeared in Scientific Reports and was written by a group of authors from the UK, Russia and Azerbaijan. The first author was Valentina Zharkova, a mathematician/astrophysicist at Northumbria University, whose group reported having received funding for the work from the U.S. Air Force and the Russian Science Foundation.  

The paper purported to find that fluctuations in the sun’s magnetic field are making the earth hotter:

Four retractions follow misconduct inquiry at U Maryland

The Journal of Virology has retracted three papers, and corrected two others, by a group led by a researcher at the University of Maryland, for problematic images. 

The articles, published in 2008 and 2014, describe experiments to assess the immune response to Newcastle disease virus in various animal species.  The studies were led by Siba K. Samal, a molecular biologist at the Virginia-Maryland Regional College of Veterinary Medicine at the University of Maryland, in College Park.

The retractions make four for Samal, who also lost a 2015 paper in the Journal of Clinical Microbiology, “Glycoprotein-based enzyme-linked immunosorbent assays for serodiagnosis of infectious laryngotracheitis,” and whose work has been scrutinized on PubPeer for more than four years. The notice for that paper reads:

Software error grounds pigeon-smarts paper

Pigeons definitely get a bad rap. Some might consider them mere rats with wings, purveyors of pestilence, distributors of dung, but rock doves aren’t, well, as dumb as their name might suggest. Pigeons are perhaps the world’s most accurate homers, they seem to have an innate knack for game theory and they can detect breast cancer in mammograms better than many doctors. 

So when researchers in Germany reported in 2017 that pigeons were as adept, if not better, than people in multitasking, the findings seemed plausible. The study, which appeared in Current Biology, garnered a bit of media attention, including this piece in The Scientist, and has been cited five times, according to Clarivate Analytics Web of Science.

Turns out, that was a flight of fancy.

Lancet journal retracts letter on coronavirus because authors say it “was not a first-hand account” after all

The Lancet Global Health has swiftly retracted a letter to the editor purportedly describing the experience of nurses treating coronavirus in Wuhan, China, just two days after it was published, because the authors are now saying it “was not a first-hand account.”

In the original letter, the authors write:

Letter on vaping science paper earns expression of concern because author made up a degree

Leonard Zelig, meet Zvi Herzig.

The journal Circulation has issued an expression of concern about a 2015 letter, putatively written by Herzig, in which the author poked holes in a review article about e-cigarettes. 

According to the EoC, however, Herzig, like Zelig, may be a bit of a chameleon.
