A distorted record on blood pressure drugs: Why one group is trying to clean up the literature

In 2015, a group of researchers based in Spain decided to write a review article on high blood pressure. But when they looked over eight articles co-authored by the same person, they noticed some undeniable similarities. Over the last few years, Giuseppe Derosa, based at the University of Pavia in Italy, has racked up 10 … Continue reading A distorted record on blood pressure drugs: Why one group is trying to clean up the literature

The authors have defended the papers as being decidedly … Continue reading Authors defend publishing clinical trial six times, even as they earn two more retractions

Weekend reads: Ghost authors proliferate; science goes to the movies; pricey grant fraud

The week at Retraction Watch featured the results of a massive replication study, yet another retraction for Diederik Stapel, and a messy situation at PLOS. Here’s what was happening elsewhere:

“Exactly the same clinical study” published six times

A group of researchers conducted a clinical trial on hundreds of hypertensive patients. Then, they published the results…six times. The “nearly identical” papers came to our attention via a retraction in Inflammation. Editor in chief Bruce Cronstein explained how he learned of the mass duplication: The editors were contacted en masse by somebody doing a Cochrane Review … Continue reading “Exactly the same clinical study” published six times
