What Caught Our Attention: When the New England Journal of Medicine (NEJM) publishes a correction that is more than a misspelling of a name, we take a look. When NEJM publishes a 500-word correction to the data in a highly cited article, we take notice. This study tested the effects of a drug to prevent blood loss in patients undergoing heart surgery; it’s been the subject of correspondence between the authors and outside experts. The correction involved tweaks — lots of tweaks — to the text and tables, which did not change the outcomes. Continue reading Caught Our Notice: Big journal, big correction
A former graduate student at the University of Hong Kong confessed to making “inappropriate modifications” to several figures in a 2013 paper in the Journal of Biological Chemistry (JBC).
According to the retraction notice, the authors identified issues in 13 images while reviewing the data; the paper’s first author, Yingying Lu, copped to manipulating the figures. Even though “these modifications did not change the results or interpretations of this work,” the authors requested the paper be retracted.
The paper’s corresponding author, Jainbo Yue, previously based at the University of Hong Kong and now at the City University of Hong Kong, had nothing to add to the retraction notice, and told us that a “third person” is repeating the key experiments.
Researchers have corrected three studies published in the journal Diabetes after users flagged issues with the images on PubPeer.
All three papers share a number of authors, including the same last and corresponding author, Aimin Xu, from The University of Hong Kong.
Since the corrections appear relatively extensive, we asked the journal if retractions were ever on the table. According to Chris Kohler, associate publisher, scholarly journals at American Diabetes Association, which publishes Diabetes, an ethical panel reviewed the papers before allowing the authors to issue the errata, all of which were published online this month: Continue reading Authors fix three Diabetes papers flagged for image issues
A paper at the center of a high-profile case of alleged misconduct in Hong Kong has earned a correction notice.
The correction replaces an expression of concern on the Journal of the American Chemical Society (JACS) paper, which followed allegations of data manipulation. It provides some un-cropped images, and removes a co-author from the paper. However, it does not appear to address previous allegations of misconduct, nor a recent ruling from an investigation at Hong Kong University (HKU), which found that some of the data were “invalid.”
The author of a paper “under editorial review” at the Journal of the American Chemical Society has told us the results the paper have been replicated, contrary to claims made by a former member of her lab.
What’s more, the author said she has submitted a correction to the paper, which is currently flagged with an expression of concern, to provide uncropped images.
We originally reported on the case in February from the perspective of Roger Wong, a former chemist at Hong Kong University who said he hasn’t been able to replicate the findings out of the lab of Dan Yang, a current chemistry professor at HKU (who is female, despite the fact that “Dan” is frequently used as a male name in English). We unfortunately failed to reach Yang in February because of an email glitch; once we contacted Yang, she told us she does not believe Wong’s side of the story:
A group of researchers in Hong Kong and China have lost a pair of papers on liver transplantation after concerns were raised about the “origin of images” in the two studies.
The articles appeared in the American Journal of Transplantationin January and February of 2006, and came from the lab of S. T. Fan, of the University of Hong Kong. When the authors were asked about the images, they “were unable to satisfactorily mitigate the concerns.”
