A reviewer, R1, brought to our attention several suspected cases of plagiarism in paper A1, submitted by authors A.
The main concerns were:
— large parts of paper A1 resembled paper B submitted by a different group of authors B, with one of the most major changes being a change in the observation day;
— large parts of a section were taken from paper C by author C, including an entire figure;
— other sentences were copied from other papers.
