Researchers have retracted and replaced a June 2016 paper in JAMA Internal Medicine after discovering errors in their data.
The paper explored whether Accountable Care Organizations (ACOs) — groups of health care providers who earn more when they deliver high-quality care without boosting costs — improve care and lower health care costs for Medicare patients. The paper’s corresponding author, Carrie H. Colla, and her colleagues examined Medicare data over five years and found the ACOs provided “ modest savings on average” and less hospital care.
But the data from the Centers for Medicare & Medicaid Services (CMS) contained errors. According to Colla, after the paper was published, CMS “let us know in the fall  that there were errors in the files, but weren’t able to give us final replacement files until winter.” Continue reading Errors in govt database prompt authors to retract and replace paper in JAMA journal
A chemistry journal has issued expressions of concern for three papers after a reader notified the editors of “unexplained discrepancies” in the data.
According to the notices, after the editors of Organic & Biomolecular Chemistry confirmed the problems, they contacted the corresponding author on the three papers, Pradeep Kumar—who works at the Council of Scientific and Industrial Research (CSIR)-National Chemical Laboratory in Pune, India—as well as the director of CSIR, Ashwini Kumar Nangia. The institution conducted its own internal review of the spectra and concluded the authors did not intentionally alter them.
Still, the journal and institution could not confirm the accuracy of the data, and the journal published expressions of concern to warn readers about the issues.
Here’s the expression of concern for “A general and concise asymmetric synthesis of sphingosine, safingol and phytosphingosines via tethered aminohydroxylation:”

A 2011 chemistry paper required corrections so extensive that the author published the changes as a second, longer paper.
Both papers, published in the Chinese Journal of Chemistry, described the synthesis of a
protein molecule with potential therapeutic applications in cancer. But when the paper’s corresponding author Yikang Wu tried to continue the work, he discovered that a substantial part of the 2011 study was incorrect.
The original paper is not marked with any editor’s note, even though the new paper — which is three pages longer than the 2011 version — acknowledges it is a “partial retraction/correction of previous results.” The new paper does appear in the list of “related content” for the 2011 article.
Given the errors, in the 2017 paper, Wu and his co-authors write: Continue reading Chemistry journal issues correction longer than original paper
In June, Gene Emery, a journalist for Reuters Health, was assigned to write a story about an upcoming paper in the Journal of the American College of Cardiology, set to come off embargo and be released to the public in a few days. Pretty quickly, he noticed something seemed off.
Emery saw that the data presented in the tables of the paper — about awareness of the problem of heart disease among women and their doctors — didn’t seem to match the authors’ conclusions. For instance, on a scale of 1 to 5 rating preparedness to assess female patients’ risk (with 5 being the most prepared), 64% of doctors answered 4 or 5; but the paper said “only a minority” of doctors felt well-prepared (findings echoed in an accompanying press release). On Monday June 19, four days before the paper was set to publish, Emery told the corresponding author — C. Noel Bairey Merz, Medical Director of the Women’s Heart Center at Cedars-Sinai in Los Angeles — about the discrepancy; she told him to rely on the data in the table.
But the more Emery and his editors looked, the more problems they found with the paper. They alerted the journal hours before it was set to publish, hoping that was enough to halt the process. It wasn’t.

A journal has retracted a 2016 paper after receiving criticism from outside researchers who raised concerns about its methodology and data.
The paper shares multiple authors with another paper that linked the vaccine for human papillomavirus (HPV) to behavioral problems in mice. Last year, a journal removed the study; later that year, the authors published a revised version in another journal. The latest retracted paper focuses on the antibodies present in a form of lupus.
Yehuda Shoenfeld at Tel-Aviv University in Israel, the corresponding author on both this latest retraction and the HPV vaccine paper, recently edited a textbook that explored how vaccines can induce autoimmunity in some people. He told us the 2016 lupus paper does have a link to vaccines [his emphasis]:

One of the world’s most prestigious mathematics journals has issued what appears to be its first retraction.
The Annals of Mathematics recently withdrew a 2001 paper exploring the properties of certain symmetrical spaces.
What prompted this retraction? And why did it occur 16 years after the paper was published? Continue reading Author “shocked” after top math journal retracts paper
In March 2016, researchers in Switzerland and Canada published a meta-analysis in The Lancet, exploring the optimal painkiller and dose for treating pain in knee and hip osteoarthritis. Soon after, the authors were informed of an error that would change “all numbers” in a paper that may influence clinical practice.
The authors contacted The Lancet immediately, in July 2016, to inform them of the issue. Sven Trelle, the paper’s corresponding author, also told us: Continue reading Lancet retracts (and replaces) paper a year after authors report error that changes “all numbers”
A 2016 study in New England Journal of Medicine has received a substantial correction, which affected several aspects of the article.
Typically, an error that affects so much of a paper would undermine the results (and possibly lead to a retraction). But in this case, the revised dose calculations actually strengthened the findings, according to the first author.
The NEJM study aimed to clarify whether patients with a neuromuscular disease called myasthenia gravis benefit from a surgical procedure to remove the thymus. About half of the patients received surgery plus the steroid prednisone, while the rest only received the steroid. The researchers found patients who received the surgery fared better.
Shortly after the paper was published in August 2016, the authors discovered an error in the calculation of the average prednisone dose. According to Gil Wolfe, the first author of the paper, when the researchers corrected the error: Continue reading Big corrections usually weaken findings. But a recent NEJM one strengthened them, author says
Sometimes, even a short notice catches our attention.
Such was the case with a recent retraction issued by Oncotarget for a 2016 paper related to the genetics that drive cancer.
Here’s the notice:

A Rutgers computer scientist is retracting conference proceedings via an unusual channel: his personal blog.
On April 7, Anand Sarwate wrote that he was retracting a mathematical proof from the proceedings from the 2016 IEEE International Conference on Acoustics, Speech, and Signal Processing (ICASSP), after discovering errors that invalidated the result.
He explains in the blog post why the mistake occurred:
