The Joy of Cooking, vindicated: Journal retracts two more Brian Wansink papers

Brian Wansink

In February of this year, the Joy of Cooking launched what you could call an epic Twitter stream. Inspired by Stephanie Lee’s reporting in BuzzFeed on Brian Wansink — the food marketing researcher at Cornell who later resigned following findings of misconduct by the university — the legendary cookbook pointed out all that was wrong with a 2009 study claiming that their recipes added calories over the years. Those tweets led to coverage in The Verge, The New Yorker, and elsewhere.

This week, the Annals of Internal Medicine retracted that paper, along with another. That brings Wansink’s tally of retracted papers to 17, with one of the papers retracted twice. (And no, 17 is nowhere near a record; he’s not even among the 30 authors with the most retractions in the world.) As Retraction Watch readers will likely recall, his work began to unravel when, after a 2016 blog post in which Wansink seemed to endorse p-hacking, four researchers joined forces to analyze his work.

Here’s the notice for 2009’s “The Joy of Cooking Too Much: 70 Years of Calorie Increases in Classic Recipes,” a paper that has been cited 20 times, according to Clarivate Analytics’ Web of Science: Continue reading The Joy of Cooking, vindicated: Journal retracts two more Brian Wansink papers

In major shift, medical journal to publish protocols along with clinical trials

AIMA major medical journal has updated its instructions to authors, now requiring that they publish protocols of clinical trials, along with any changes made along the way.

We learned of this change via the COMPare project, which has been tracking trial protocol changes in major medical journals — and been critical of the Annals of Internal Medicine‘s response to those changes. However, Darren Taichman, the executive deputy editor of the journal, told us the journal’s decision to publish trial protocols was a long time coming: Continue reading In major shift, medical journal to publish protocols along with clinical trials

Top journals give mixed response to learning published trials didn’t proceed as planned

Ben Goldacre has been a busy man. In the last six weeks, the author and medical doctor’s Compare Project has evaluated 67 clinical trials published in the top five medical journals, looking for any “switched outcomes,” meaning the authors didn’t report something they said they would, or included additional outcomes in the published paper, with no explanation for the change. The vast majority – 58 – included such discrepancies. Goldacre talked to us about how journals – New England Journal of Medicine (NEJM), JAMA, The Lancet, BMJ, and Annals of Internal Medicine — have responded to this feedback.

Did a clinical trial proceed as planned? New project finds out

A new project does the relatively straightforward task of comparing reported outcomes from clinical trials to what the researchers said they planned to measure before the trial began. And what they’ve found is a bit sad, albeit not entirely surprising.

As part of The Compare Project, author and medical doctor Ben Goldacre and his team have so far evaluated 36 clinical trials published by the top five medical journals (New England Journal of Medicine, the Journal of the American Medical Association, The Lancet, Annals of Internal Medicine, and British Medical Journal). Many of those trials included “switched outcomes,” meaning the authors didn’t report something they said they would, or included additional outcomes in the published paper, with no explanation for the change.

Here are the latest results from the project, according to its website:

Heart researcher who faked patient data gets third retraction

Screen Shot 2015-11-06 at 6.38.09 PMA heart researcher has notched her third retraction, a small 2006 trial in Annals of Internal Medicine which seemed to show that a blood pressure drug could help people with artery disease walk further with less pain.

Earlier this year, Anna Ahimastos, formerly a researcher at Baker IDI Heart and Diabetes Institute in Melbourne, lost a larger clinical trial in JAMA and a subanalysis in Circulation Research after it was discovered she’d fabricated patient records. As principle investigator Bronwyn Kingwell told us in September:

Specifically, records were fabricated for trial participants that did not exist.

Now, following an investigation by the institute, her co-authors are proactively retracting papers, with more to come. The Annals of Internal Medicine paper, “Ramipril Markedly Improves Walking Ability in Patients With Peripheral Arterial Disease,” is being pulled due to an “inability to adequately validate primary data sources.” According to the note, Ahimastos “maintains the integrity of the data and validity of reported results:”

March Madness? Harvard profs take shots at controversial studies, request retractions

harvardIn the wake of Harvard’s gritty performance in the NCAA men’s basketball tournament — they were eliminated Saturday — a pair of faculty members at the Ivy League institution are calling foul on two controversial journal articles that have already been corrected.

Walter Willett, an oft-quoted Harvard nutrition expert, is calling for the retraction of an eyebrow-raising article earlier this month challenging the relative health benefits of fats from fish and vegetables over those in meat and butter.

The article, which appeared in the Annals of Internal Medicine, quickly came under fire and the researchers — from the University of Cambridge — ended up making several corrections. Despite the changes, the authors have stood by their work, according to a piece this week in Science.

But that hasn’t stopped Willett from urging a retraction. Per Science:
