In a first, U.S. CDC retracts, replaces study about suicide risk in farmers

In a first for the CDC, the agency’s premier scientific publication has retracted a 2016 article on suicide, five months after a news story pointed out serious errors in the paper.

The article, initially published as “Suicide Rates by Occupational Group — 17 States, 2012,” had purported to find that farmers were at particularly high risk of suicide. That result in particular caught the attention of a website called The New Food Economy (TNFE), which last June called out what it said were errors in the CDC’s analysis. And on June 29, the journal, the Morbidity and Mortality Weekly Report (MMWR), issued a reader’s note.

As TNFE wrote, the crux of the mistake involves the misclassification of farmer suicides in a way that significantly inflated the rate of these events — errors the website said it first raised with the CDC in April 2018: Continue reading In a first, U.S. CDC retracts, replaces study about suicide risk in farmers

Judge dismisses most of Carlo Croce’s libel case against the New York Times

Carlo Croce

Carlo Croce, a prolific cancer researcher at The Ohio State University in Columbus who was the subject of a front page story in The New York Times last year about allegations of misconduct against him, has had most of a lawsuit he filed against the newspaper thrown out.

As first reported by Courthouse News Service, United States District Judge James Graham tossed all but one of Croce’s claims for defamation against the Times and two of its reporters. That claim — which involved a statement in a letter that reporter James Glanz sent Croce as part of his reporting — survived dismissal, but not on grounds that it inflicted emotional distress, Graham ruled.

The March 2017 story ran on the front page of the Times under the headline “Years of Ethics Charges, but Star Cancer Researcher Gets a Pass:” Continue reading Judge dismisses most of Carlo Croce’s libel case against the New York Times

Data mishap forces retraction of paper on gun laws, domestic killings

The authors of a 2018 paper on the effects of gun laws on domestic violence have retracted the article after discovering errors in their analysis and replaced it with a clean version. The new study shows that some gun laws — particularly ones that keep firearms out of the hands of violent offenders, even if their offenses don’t involve domestic assaults — do seem to reduce the incidence of domestic killings.

The paper, which appeared last November in the American Journal of Epidemiology and received some press coverage, including this piece in the New York Times, looked specifically at whether laws that keep guns away from people convicted of violent crimes beyond domestic abuse reduce the number of intimate partner homicides. It also considered the effect of laws that covered dating partners and not simply spouses or former spouses. The first author is April Zeoli, of Michigan State University. Zeoli has published other papers on the topic and delivered a TEDMED talk on it as well.

According to the abstract of the article: Continue reading Data mishap forces retraction of paper on gun laws, domestic killings

Aerospace researchers in Japan up to three retractions

Rachid Amrousse

A pair of researchers in Japan has lost their third paper in a UK journal, which cites problematic images and an institutional investigation for the move.

The 2016 article, “Novel Rh-substituted hexaaluminate catalysts for N2O decomposition,” was written by Rachid Amrousse and Akimasa Tsutsumi, of the Japan Aerospace Exploration Agency, or JAXA, in Sagamihara. It appeared in Catalysis Society & Technology, a publication of the Royal Society of Chemistry, and has been cited seven times, according to Clarivate Analytics’ Web of Science.

Allow us to explain that headline.

Food Science & Nutrition has retracted a 2018 article by a group of researchers in China and Pakistan for plagiarism. The article was titled “Experimentally investigated the asparagus (Asparagus officinalis L.) drying with flat-plate collector under the natural convection indirect solar dryer.”

JAMA journal retracts paper when author can’t produce original data

In July 2017, a JAMA journal called for an investigation into a 2013 paper it had published after concluding that the article had “scientific and ethical concerns.” Now the journal, JAMA Otolaryngology − Head & Neck Surgery, is retracting the paper.

The article, “Dexamethasone for the prevention of recurrent laryngeal nerve palsy and other complications after thyroid surgery: a randomized double-blind placebo-controlled trial,” came from a group in Italy led by Mario Schietroma, of the Department of Surgery at the University of L’Aquila, in Abruzzo, Italy. Schietroma, who in December admitted to us that a retracted 2015 paper of his in the Journal of the American College of Surgeons suffered from “misinterpretation of the statistical data,” now has four retractions.

The paper has been cited a total of 18 times, according to Clarivate Analytics’ Web of Science, including twice since it was subjected to an expression of concern. One of those citations was by a Cochrane systematic review.

When researchers from a particular country dominate retraction statistics, what does it mean?

Iekuni Ichikawa

The Retraction Watch Leaderboard of authors with the most retractions is a frequent source of comment and speculation. Why do only men appear on it? And what fields and countries are represented? Here, Iekuni Ichikawa, Project Professor at Shinshu University and Emeritus Professor of Pediatrics at Vanderbilt University, as well as a co-founder of the Association for the Promotion of Research Integrity (APRIN) in Japan, takes a look at a recent story that referenced our leaderboard — and what those figures really mean.

The authors of Retraction Watch often take pains to point out that the relative rarity of retractions — despite dramatic increases in their rates — make studying them a challenge. But it is often difficult to resist seeking out truth in retraction numbers.

As a case in point, in August Science published an article by Kai Kupferschmidt about research misconduct in Japan that quoted data from the Retraction Watch Leaderboard, pointing that out that although “half of the top 10 are Japanese researchers…only about 5% of published research comes from Japan.” Continue reading When researchers from a particular country dominate retraction statistics, what does it mean?

Graduate student in China stripped of PhD after investigation that led to a dozen retractions

On Friday we reported on the case of a group of researchers in China who have retracted at least 11 papers for various kinds of misconduct. Here’s a bit more on that story, courtesy of our commenters.

First, it turns out that the retraction total is at least 12. But more significant is that the institution in question, Tsinghua University’s Graduate School at Shenzhen, announced yesterday that it had stripped one of the researchers involved in the studies of his PhD and sanctioned another in the matter. Continue reading Graduate student in China stripped of PhD after investigation that led to a dozen retractions

Group in China earns nearly a dozen retractions for image duplication, forged authorship, and more

A group of materials scientists in China has earned 11 retractions and three corrections — so far — for image manipulation, duplication, deceptive authorship and other misconduct.

The papers, from a group at the prestigious Tsinghua University, appeared in a variety of materials journals and date back to 2014. The most recent publications arrived in 2016.

[Please see an update on this post.]

The notices read pretty much the same way. Here, for example, is the retraction statement for “Effects of high-energy electro-pulsing treatment on microstructure, mechanical properties and corrosion behavior of Ti–6Al–4V alloy,” which was published in 2015 in Materials Science and Engineering C, an Elsevier title: Continue reading Group in China earns nearly a dozen retractions for image duplication, forged authorship, and more

“Sufficiently serious” issues in study prompt company to yank drug approval application in China

The maker of a leading over-the-counter antacid has withdrawn its application for approval of the drug in China because a clinical trial of the product in that country was marred by “major protocol deviations.”

Researchers for the company, Reckitt Benckiser, maker of Gaviscon, had published a report on the study in 2015 in the journal Alimentary Pharmacology & Therapeutics. But the journal has now retracted the article, “Randomised clinical trial: The clinical efficacy and safety of an alginate‐antacid (Gaviscon Double Action) versus placebo, for decreasing upper gastrointestinal symptoms in symptomatic gastroesophageal reflux disease (GERD) in China,” at the behest of the drug maker.
