After a publisher learned there may be issues with a 2008 diabetes paper, it asked the author’s university to investigate. The university found evidence of image duplication, and asked the journal to consider correcting the paper.
Instead, the journal has retracted it.
The backstory involves diabetes researcher Kathrin Maedler, who has one previous retraction, as well as multiple corrections.
