Publisher flags more than 120 papers three and a half years after learning of problems What started as a small editorial conundrum several years ago has turned into an expression of concern for dozens of papers in a medical journal, thanks to the work of an Australian physician and s…

A Retraction Watch story left one reader intrigued. “I’ve never seen anything like that before,” said John Loadsman of the University of Sydney, an anesthesiologist and journal editor. “I thought, I’ve got to have a look.”

Depressing that a huge proportion of image misconduct is in Cancer research.

Paper published 20 years back. Clear signs of Photoshop. First reports on PubPeer was 2024. @grumpygasbag.bsky.social pointed to more problems. I have just done another animation based on that.

Put pressure on publishers to follow best practice — external regulation is the answer Journals that work hard to meet the needs of both authors and readers should be acknowledged publicly — encouraging others to follow suit.

@j-clin-anesth.bsky.social @elsevierconnect.bsky.social this problem was also brought to your attention more than two years ago. Surely something needs to be done here… pubpeer.com/publications...

Screenshot of the original published figure (left) and the corrected figure (right). In the left photo we see tumors in a grid of 5 columns and 6 rows. Two sets of tumors are marked by me with blue and green boxes respectively. 
In the right photo the duplicated tumors are just left out.

Hey @tandfresearch.bsky.social, - you should not allow authors to address photoshopped tumors by just leaving out the photoshopped tumors. This paper was 1 year old at the time of correction. Where are the originals?
Horrible editorial decision.

@annsaudimed.bsky.social you might want to ask the authors to address some questions that have been raised about their paper pubpeer.com/publications...

I’m certainly not surprised. I haven’t found another editor yet who makes more than a cursory attempt to check the registration (rare), if at all (usual). It’s not only necessary to check the registration exists, but also the history of changes, the original version sometimes bearing no resemblance

This is different. Eyeglasses and candles for mean markers. Perhaps the editor(s), reviewers and Wiley could have borrowed the candles and glasses to help them see the problems with the error bars pubpeer.com/publications...
