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:

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:

Lancet Oncology updates conflicts of interest statement for cancer-cell phone paper

lanoncThe Lancet Oncology is correcting a 2011 article about the cancer risks of radiofrequency electromagnetic fields, such as those from cell phones, to clarify information about potential conflicts of interest for one of the experts who was involved in its preparation.

The assessments appeared as a monograph for the International Agency for Research on Cancer (IARC).

However, after the 2011 paper “Carcinogenicity of radiofrequency electromagnetic fields” appeared, a reader raised allegations of conflicts of interest among its participants, which sparked a reconsideration of their disclosures.

The correction concerns the conflicts of interest for Niels Kuster of the Swiss Federal Institute of Technology in Zurich, also a board member of the non-profit IT’IS foundation.

Kuster told Retraction Watch he disclosed everything upfront:

Duplication of “a major part of text and results” adds up to third retraction for mathematician

An article by Alexander Spivak, a mathematician based in Israel, is being retracted from the proceedings of a 2014 numerical analysis meeting because Spivak had already published “a major part of text and results” in a mathematics journal in 2010.

Spivak, a member of the faculty of sciences at Holon Institute of Technology, has a bit of a history with the journal that published his initial 201o paper, the International Journal of Pure and Applied Mathematics. That journal retracted two of his papers last year after learning from Zeev Schuss, Spivak’s post-doc supervisor at Tel Aviv University, that those papers contained plagiarized chunks from a paper by Schuss and two colleagues.

Here’s more from the retraction notice for “Successive approximations for optimal control in some nonlinear systems with small parameter”, published in the Proceedings of the 6th International Conference on Numerical Analysis:

Fungus among us, but what kind? Typing error spawns retraction for mushroom paper

natprodresAs every mushroom lover knows, weekend mycology is no sport for the lily-livered. Tasty species often look awfully like their deadly cousins. Turns out, typing can even be problematic for the experts.

Natural Products Research is retracting a 2014 paper on shelf fungus because… well, it wasn’t about shelf fungus after all.

The paper, “Chemical constituents: water-soluble vitamins, free amino acids and sugar profile from Ganoderma adspersum,” was written by Ibrahim Kivrak, a food chemist at Mugla Sitki Kocman University in Mugla, Turkey. It analyzed the nutritional components of G. adspersum, and found, per the abstract:

Flood paper washed away after “oversight” leads to publication of wrong manuscript

JEHSEThe editor of the Journal of Environmental Health Science and Engineering has retracted a paper mapping flood zones in Iran because the authors mistakenly uploaded a manuscript that had already been published elsewhere.

According to corresponding author Majid Bagheri of K.N. Toosi University of Technology in Tehran, a different paper on wastewater treatment was accepted and peer-reviewed at JEHSE, but then the authors uploaded the wrong manuscript, and that manuscript, on flood zones, made it all the way through acceptance and publication due to an “oversight.”

The retracted version of the paper was published online on December 27, 2014 in JEHSE, a BioMed Central title. The preceding, non-retracted version, was published online at the Arabian Journal for Science and Engineering just four days earlier, on December 23, 2014.

Here is Bagheri’s account: Continue reading Flood paper washed away after “oversight” leads to publication of wrong manuscript

Scientists “wish to resign as co-authors:” Quantum dot paper retracted

chemcommChemical Communications has retracted a 2015 article by a group of researchers in China over concerns about fabricated data and an incredible shrinking list of authors.

The paper, “N, S co-doped graphene quantum dots from a single source precursor used for photodynamic cancer therapy under two-photon excitation,” was ostensibly written by nine researchers at the Collaborative Innovation Center for Marine Biomass Fiber, Materials and Textiles of Shandong Province, the Shandong Sino-Japanese Center for Collaborative Research of Carbon Nanomaterials, Laboratory of Fiber Materials and Modern Textiles, the Growing Base for State Key Laboratory at the  College of Chemical Science and Engineering at Qingdao University, and Mayo Clinic, in Rochester, Minn.

According to the abstract: Continue reading Scientists “wish to resign as co-authors:” Quantum dot paper retracted

Geology dust-up: Second sand paper swept away for duplication

GeomorphologyCiting an “abuse of the scientific publishing system,” the editors of Geomorphology have retracted a paper from a quartet of geologists in China for containing “significant similarity” to four other papers.

It is the second recent retraction for the group: In a loop of self-plagiarism, the Geomorphology paper was cited as a source of copied material in a retraction last month from Sedimentary Geology.

This most recent retraction is of a January 2014 paper, “The influence of sand bed temperature on lift-off and falling parameters in windblown sand flux,” analyzing the rise and fall of windblown sand based on the temperature of the sand bed.

Here is the full text of the notice:
