After doing some digging, we’ve learned more about the “potential problem.”
Apparently, the retraction was requested by Nanyang Technological University (NTU) in Singapore. NTU has been investigating the first author for months, after it received an allegation about an unrelated manuscript. As a result, NTU terminated first author Hamidreza Namazi‘s contract as a research fellow earlier this year.
As part of the investigation, NTU began to look at Namazi’s other papers, and discovered several with potential problems — including this one, which NTU believes did not receive proper ethical approvals. So it contacted the journal to raise its concerns.
Namazi, however, told us that he and his colleague obtained approval from another organization, but didn’t make that clear in the paper — so the journal has retracted its retraction notice while it investigates Namazi’s claim.
