Authors retract surgery study that claimed to be randomized but wasn’t

spine-coverThe authors of a study about spinal fusion surgery have retracted it after realizing the cohort study was described as a prospective, randomized trial. 

The last author told us he believed the incorrect wording was added to the paper — and the title — by accident. Even though he said the journal Spine suggested correcting it, the authors chose to retract the paper entirely.

The abstract of the study describes the design as a:

Prospective, randomized, controlled trial.

But according to the retraction notice for “Prospective, randomized, controlled trial of silicate-substituted calcium phosphate versus rhBMP-2 in a minimally invasive transforaminal lumbar interbody fusion,” the abstract was not accurate:

Fraudster loses third attempt to remove 7-year debarment

court caseA U.S. judge has denied a virology researcher’s third attempt to overturn a seven-year debarment from receiving federal funds, following a 2010 decision by the U.S. Office of Research Integrity.

The ORI banned Scott Brodie for seven years after concluding he had committed 15 acts of misconduct at the University of Washington. The deception affected grant applications, published papers, manuscripts, and presentations. Since then, Brodie has tried multiple times to reverse the ruling in court.

In the latest decision, dated June 13, United States District Judge James E. Boasberg writes: Continue reading Fraudster loses third attempt to remove 7-year debarment

Columbia investigation reveals researcher faked data — and a degree

InnateImmunityA researcher faked data and a masters degree, according to an investigation by Columbia University.

He’s also earned his fourth retraction. The new notice, along with one we’ve uncovered from 2014, provide some information on the extent of the deception of Robert Frumento, who left Columbia a decade ago, around the time that the now-retracted papers were published.

Here’s the new retraction notice:

Author denies accusations of blatant duplication

NPGTwitter is abuzz today over allegations that a recent paper in Scientific Reports contains a blatant example of duplication.

According to the allegations, a group of researchers in Malaysia have used the same four images to represent some 30 cells at different stages of cell death. One researcher has even suggested the allegedly doctored images appear in three different papers.

Is this a manipulated image? See for yourself:

Pharmacology journal pulls paper for “insufficient scientific quality;” authors disagree

Frontiers in PharmacologyAgainst the authors’ wishes, a pharmacology journal has retracted a paper after receiving two messages questioning the “soundness of the experimental results.”

The editors of the journal, Frontiers in Pharmacology, issued an expression of concern about the paper in April 2016, and investigated it following the allegations. According to the retraction notice, the authors disagree with the retraction.

Here’s the retraction notice for the paper: Continue reading Pharmacology journal pulls paper for “insufficient scientific quality;” authors disagree

“All co-authors are honorary:” Team earns fifth retraction

Movement DisordersA team of researchers from Japan has earned a fifth retraction, after co-authors told the journal that they did not participate in much of the paper.

Yoshihiro Sato, listed at Mitate Hospital, is the only author of the paper who was not “honorary,” the managing editor of the journal confirmed. He and the same co-authors recently lost three other papers about preventing hip fractures for “concerns regarding data integrity” and authorship issues — one of those papers, published in JAMA, specified that Sato was responsible for the data. All four authors were also included in a retraction last year of a paper with “concerns about the underlying data;” there, too, Sato said his co-authors were named “for honorary reasons.”

Here’s the retraction notice for “Alendronate and vitamin D2 for prevention of hip fracture in Parkinson’s disease: A randomized controlled trial,” published in Movement Disorders:

PLOS ONE retracts 2 malaria papers over doubts experiments ever took place

PLOS One

Authors have retracted a pair of PLOS ONE papers after an investigation suggested the articles might contain some fiction.

In the papers, the authors describe collecting and analyzing the DNA of mosquitoes to look for changes following the introduction of bed nets treated with insecticides to combat malaria. However, an investigation by the Institut de Recherche pour le Développement in France could not confirm some of the experiments ever took place.

Here’s the retraction notice for “How the Malaria Vector Anopheles gambiae Adapts to the Use of Insecticide-Treated Nets by African Populations,” which appears at the top of the paper:

Pro-lifers call for JAMA to retract 2005 paper about fetal pain

JAMAPro-life activists have asked JAMA to retract a 2005 paper that suggested fetuses can’t feel pain before the third trimester.

Critics are arguing that newer findings have shown pain sensation appears earlier in gestation, yet the 2005 data continue to be cited in the discussion around abortion. What’s more, they note, some of the authors failed to mention their ties to the abortion industry.

The 2005 paper has been cited 191 times, according to Thomson Reuters Web of Science. We spoke with Howard Bauchner, Editor in Chief at JAMA and The JAMA Network, who told us something similar to what he said last week, when PETA asked to retract a paper they claim could be harmful to elephants: Continue reading Pro-lifers call for JAMA to retract 2005 paper about fetal pain

Conservative political beliefs not linked to psychotic traits, as study claimed

American Journal of Political Science

Researchers have fixed a number of papers after mistakenly reporting that people who hold conservative political beliefs are more likely to exhibit traits associated with psychoticism, such as authoritarianism and tough-mindedness.

As one of the notices specifies, now it appears that liberal political beliefs are linked with psychoticism. That paper also swapped ideologies when reporting on people higher in neuroticism and social desirability (falsely claiming that you have socially desirable qualities); the original paper said those traits are linked with liberal beliefs, but they are more common among people with conservative values.

We’re not clear how much the corrections should inform our thinking about politics and personality traits, however, because it’s not clear from the paper how strongly those two are linked. The authors claim that the strength of the links are not important, as they do not affect the main conclusions of the papers — although some personality traits appear to correlate with political beliefs, one doesn’t cause the other, nor vice versa.

In total, three papers have been corrected by authors, and a correction has been submitted on one more.

We’ll start with an erratum that explains the backstory of the error in detail. It appears on “Correlation not Causation: The Relationship between Personality Traits and Political Ideologies,” published by the American Journal of Political Science: Continue reading Conservative political beliefs not linked to psychotic traits, as study claimed

Another paper by Duke pair with 12+ retractions is flagged

American Journal of Respiratory and Critical Care MedicineAnother expression of concern (EOC) has appeared for a pair of lung researchers formerly employed by Duke University.

Co-authors Erin Potts-Kant, a research assistant who left the school and was charged with embezzlement, and Michael Foster, who has retired, share more than a dozen retractions, corrections and EOCs.

Like many of those papers, the American Journal of Respiratory and Critical Care Medicine is being flagged over concerns it is “unreliable.” Here’s more from the EOC:
