JAMA issues mega-correction for data breach letter due to “wording and data errors”

s_cover_jcv062315A JAMA letter published in April on data breaches accidentally included some data that shouldn’t have been published, either — specifically, “wording and data errors” that affected five sentences and more than 10 entries in a table. One result — a reported increase in breaches over time — also went from statistically significant to “borderline” significant, according to the first author. (So yeah, this post earns our “mega correction” category.)

According to an author, an “older version” of a table made it into the letter, “Data Breaches of Protected Health Information in the United States,” which was corrected in the journal’s June 23/30 issue.

The letter and table in question detail 949 breaches of “unencrypted protected health information.”  The letter says the number of breaches has increased from 2010 to 2013; the original article claimed that the P value on that increase was <.001, but the correction says it’s really 0.07. The original says 29.1 million personal records were affected in those breaches; the real number is 29.0. And so on.

To catch a cheat: Paper improves on stats method that nailed prolific retractor Fujii

anaesthesiaThe author of a 2012 paper in Anaesthesia which offered the statistical equivalent of coffin nails to the case against record-breaking fraudster Yoshitaka Fujii (currently at the top of our leaderboard) has written a new article in which he claims to have improved upon his approach.

As we’ve written previously, John Carlisle, an anesthesiologist in the United Kingdom, analyzed nearly 170 papers by Fujii and found aspects of the reported data to be astronomically improbable. It turns out, however, that he made a mistake that, while not fatal to his initial conclusions, required fixing in a follow-up paper, titled “Calculating the probability of random sampling for continuous variables in submitted or published randomised controlled trials,” also published in Anaesthesia.

According to the abstract:

“The Replication Paradox:” Sans other fixes, replication may cause more harm than good, says new paper

M.A.L.M van Assen
Marcel .A.L.M van Assen

In a paper that might be filed under “careful what you wish for,” a group of psychology researchers is warning that the push to replicate more research — the focus of a lot of attention recently — won’t do enough to improve the scientific literature. And in fact, it could actually worsen some problems — namely, the bias towards positive findings.

Here’s more from “The replication paradox: Combining studies can decrease accuracy of effect size estimates,” by Michèle B. Nuijten, Marcel A. L. M. van Assen, Coosje L. S. Veldkamp, and Jelte M. Wicherts, all of Tilburg University: Continue reading “The Replication Paradox:” Sans other fixes, replication may cause more harm than good, says new paper

Cancer Research retraction is fifth for Robert Weinberg; fourth for his former student

13.coverAnother domino has fallen in a chain of retractions for Robert Weinberg, the man who discovered the first tumor-causing gene in humans, along with the first tumor suppressor gene: Cancer Research just retracted a paper of his on some of the molecular steps to metastasis.

The paper, “Concurrent Suppression of Integrin α5, Radixin, and RhoA Phenocopies the Effects of miR-31 on Metastasis,” has been cited 70 times, according to Thomson Scientific’s Web of Knowledge. As we have noted before, Weinberg’s papers are frequently highly cited. His bio at the Whitehead Institute bills him as “a pioneer in cancer research.”

Four of Weinberg’s retracted papers — including this latest — share a first author: Scott Valastyan, once a very promising grad student in Weinberg’s lab. 

This retraction, like Valastyan’s others, is linked to his retracted 2009 Cell paper. (That paper was cited 482 times, and there’s even a video from the Cell press office to go with it). Continue reading Cancer Research retraction is fifth for Robert Weinberg; fourth for his former student

Another author withdrawal from JBC earns another opaque notice

Journal of Biological Chemistry1The authors of a 2014 study on the biochemical changes that can encourage the progression of cancer have withdrawn the paper from the Journal of Biological Chemistry.

The post from the JBC – which we’ve noted are rarely helpful – doesn’t provide any details or reason for the withdrawal. As usual, this is all we got:

Weekend reads: Is failing to share data misconduct?; worst journal ever; Elsevier boycott

booksThe big news this week at Retraction Watch was the release of more than two dozen retractions for accounting researcher James Hunton, and the sentencing of Dong-Pyou Han for scientific fraud (see more below). Here’s what was happening elsewhere: Continue reading Weekend reads: Is failing to share data misconduct?; worst journal ever; Elsevier boycott

Misidentified genetic sequence causes retraction of pathogen paper one month after publication

Genome Announcements

The author of an article mapping the genome of an infectious bacterium is pulling the paper because — well, it wasn’t the bacterium she thought it was.

Study author Celia Abolnik is retracting her paper in Genome Announcements because it didn’t actually map out the DNA of Mycoplasma meleagridis, a bacterium that typically infects turkeys but has recently been found in chickens.

The trouble was, the sequence for Mycoplasma meleagridis in the National Institute of Health’s DNA database, Genbank, was actually a different variety of bacteria — Mycoplasma gallinaceum, another scourge of poultry.

Here’s the notice for “Complete Genome Sequence of Mycoplasma meleagridis, a Possible Emerging Pathogen in Chickens:”

Editors retract algae study, citing “issues with the data”

International Journal of PhytoremediationThe International Journal of Phytoremediation  has issued a retraction for a 2013 article suggesting algae could shield against gamma radiation better than lead.

Sadly, such an innovation was not to be — the editors have pulled the paper, saying:

We are now cognizant that there are issues with the data and determinations made within the manuscript that cannot be corrected through a corrigendum.

The paper is now covered by a dizzying watermark. (The first page can be seen here.)

Here’s more from the retraction for “Shielding Property of Natural Biomass Against Gamma Rays”, authored by a group of professors at Amasya University, Aksaray University, and Suleyman Demirel University in Turkey:

Corrections (and one EoC) propagate for distinguished plant biologist, Olivier Voinnet

There may be some deeply rooted issues in the work of high-profile plant biologist Olivier Voinnet, biology department research director at ETH in Zurich. Corrections have continued to pile up months after his work was hit with a barrage of criticism on PubPeer. We’ve tracked a total of seven corrections over the past five months (not including the April retraction of a 2004 paper in The Plant Cell). One of the corrected papers also received an Expression of Concern this week.

Collectively, the corrected papers have accumulated more than 1200 citations.

In January, Voinnet said he planned to correct multiple papers, after receiving “an anonymous email.”

One of the recent corrections we found is for a 2003 article in The Plant Journal, “An enhanced transient expression system in plants based on suppression of gene silencing by the p19 protein of tomato bushy stunt virus,” which details using proteins from a tomato virus to help alter gene expression. The study has been cited 862 times, according to Thomson Scientific’s Web of Knowledge. Here’s the correction notice, posted June 8:

Lancet journal removes Buddha cover art following protest

Lancet inf disThe Lancet Infectious Diseases has removed a cover illustration of the Buddha contemplating a mosquito from its June, 2015 issue — a complement to a paper about malaria treatment in Cambodia — after receiving emails from readers who protested the depiction of the statue in a non-religious context.

After publishing the cover, the journal received “several emails” protesting the image, such as this one from Arjuna P R Aluwihare:
