Breakfast study mischaracterized funding by cereal group

PLOS ONE has quickly corrected an October analysis of what children in Malaysia eat for breakfast, after the study ~~neglected to note it benefited from~~ mistakenly noted an unrestricted research grant from cereal companies supported author salaries. The grant supported the salaries of research assistants, according to the correction note.

Per the authors’ request, the journal has noted that the study received financial support from Nestlé R&D Center in Singapore and Cereal Partners Worldwide, a collaboration between General Mills Inc. and Nestlé S.A., with the goal of selling cereal outside the US and Canada. These funders provided “salaries for research assistants” for the MyBreakfast study, on which the analysis is based, according to the note.

The paper includes authors affiliated with Nestlé and Cereal Partners Worldwide, as well as a detailed “Competing interests” section, which outlines the relationships with these companies.

The correction note explains the information that should have appeared in the funding section of the article:

PLOS ONE issues editor’s note over controversial chronic fatigue syndrome research

After a request for the original data was denied, PLOS ONE editors have flagged a 2012 sub analysis of a controversial clinical trial on chronic fatigue syndrome with an editor’s note.

The editor’s note — which reads like an Expression of Concern — reiterates the journal’s policy that authors make data and materials available upon request, and notes that staff are following up on “concerns” raised about the study.

There have been numerous requests for data from the “PACE” trial, as the clinical trial is known, which the authors say they have refused in order to protect patient confidentiality. On November 13, James Coyne, a psychologist at the University Medical Center, Groningen, submitted a request for the data from the PLOS ONE paper to King’s College London, where some of the authors were based. According to Coyne’s WordPress blog (he also has a blog hosted by PLOS), the journal asked him to let them know if he “had any difficulties obtaining the data.” He did — KCL denied the request last Friday (the whole letter is worth reading):

The university considers that there is a lack of value or serious purpose to your request. The university also considers that there is improper motive behind the request. The university considers that this request has caused and could further cause harassment and distress to staff.

Last author Peter White at Queen Mary University of London, UK, told us the journal had not asked them to release the data, but he would work with PLOS to address any questions:

We understand PLOS One are following up concerns expressed about the article, according to their internal processes. We will be happy to work with them to address any queries they might have regarding the research.

Here’s the editor’s note for “Adaptive Pacing, Cognitive Behaviour Therapy, Graded Exercise, and Specialist Medical Care for Chronic Fatigue Syndrome: A Cost-Effectiveness Analysis,” in full:

Having non-replicable data may not hurt your rep, says study

Although many scientists fear putting their data to the test of replication efforts, due to the embarrassment they’d feel if their findings couldn’t be repeated, a new study suggests those fears are unfounded.

The paper, published last week in PLOS ONE, found that scientists overestimate how much having non-replicable data will hurt their careers, and the community values those who are honest about what went wrong.

Specifically, as the authors note:

Cropped, spliced image leads to a PLOS One correction

A PLOS One paper on morphine treatment for cancer cells has a couple issues with figures, prompting a massive correction — what we affectionately call a “mega-correction” — by the journal.

In one figure, there was “an undisclosed splice.” Another figure contained two panels that were “mistakenly from the same sample.”

The 2013 paper in question, “Chronic Morphine Treatment Attenuates Cell Growth of Human BT474 Breast Cancer Cells by Rearrangement of the ErbB Signalling Network,” has been cited four times, according to Thomson Scientific’s Web of Knowledge.

Here’s the correction:

Mystery: PLOS One seeks investigation after publishing two papers with “substantial overlap”

PLOS One has retracted one of two cancer papers with “substantial overlap” that were reviewed simultaneously by different editors.

This one’s a bit of a mystery — neither of the papers share an author, and no authors share institutions. Once the editors discovered the overlap, they contacted the authors. One group of authors provided the requested documentation for the experiments. The other did not — so the editors retracted that article, even though it was published months before the other one.

In the meantime, the editors have asked the authors’ institutions investigate how the articles — which contain entire identical sentences, and some extremely similar figures — were put together. According to a statement from the editors:

When the title states the wrong result, a paper gets corrected

Ever wonder why, on a round-trip, the leg home often feels shorter? A group of researchers found that’s only true in hindsight, as people look back on which leg felt shorter — the trouble is, when the paper first appeared, the title mistakenly stated the opposite was true.

One June 10, PLOS ONE published a paper entitled “The Return Trip Is Felt Longer Only Postdictively: A Psychophysiological Study of the Return Trip Effect”; 17 days later, it was republished under the correct title, “The Return Trip Is Felt Shorter Only Postdictively: A Psychophysiological Study of the Return Trip Effect.”

On July 15, the journal posted a correction notice explaining its mistake:

Stem cell researcher Jacob Hanna’s correction count updated to 10

Thanks to some eagle-eyed readers, we’ve been alerted to some corrections for high profile stem cell scientist Jacob Hanna that we had missed, bringing our count to one retraction and 13 errata on 10 papers.

The problems in the work range from duplications of images, to inadvertent deletions in figures, to failures by his co-authors to disclose funding sources or conflicts of interest. Hanna is the first or last author on 4 of the papers, and one of several on the rest.

First up, a correction to a Cell paper on which Hanna is the first author:

A mess: PLOS mistakenly publishes rejected ADHD-herbicide paper, retracts it

PLOS One has retracted a paper that links the most commonly used herbicide to ADHD, after it was “published in error.”

According to the note, the paper was “editorially rejected following peer review and consultation with the Editorial Board,” but ended up going through the production process anyway.

When we contacted the authors, they filled us in with more details.

Author’s ties to NFL lead to correction for review that cast doubt on brain risk from sports

A review paper that suggested the degenerative brain disease that’s striking former football players may not be tied to contact sports has been corrected to reveal the first author spent decades working for the National Football League.

The correction appears in a review in PLOS ONE about chronic traumatic encephalopathy – the degenerative brain disease that was the basis of a $765 million settlement for former NFL players, along with a number of similar lawsuits. It fixes incorrect statements and adds conflicts of interest, including those with with first author Joseph Maroon, who spent more than 30 years working with the NFL and seven for the wrestling group the WWE.

It appears as if all the original paper declared was that Maroon was an “unpaid consultant” to the Pittsburgh Steelers. But apparently there was a lot more to it, according to the notice:

PLoS ONE mega-correction, but no retraction, for researcher who sued diabetes journal

PLoS ONE has just issued a 12-figure correction on a paper by Mario A. Saad, who sued the American Diabetes Association unsuccessfully in an attempt to prevent it from retracting four papers in its flagship journal Diabetes.

The corrections include taking out Western blots copied from another Saad paper, as well as several figures where the bands were “misplaced.”

PubPeer commenters suggest this may not be enough, calling seven additional figures into question. Continue reading PLoS ONE mega-correction, but no retraction, for researcher who sued diabetes journal
