New England Journal of Medicine and Lancet peer reviewers did not see raw data behind findings before publication
Some of the world’s leading medical journals are reviewing their processes after they were forced to retract studies based on flawed data.
None of the peer reviewers who examined a questionable study on the impact of blood pressure medications on Covid-19 saw the raw data behind the findings before it was approved for publication in world-renowned medical journal, the New England Journal of Medicine.
The study was based on a massive dataset supposedly gathered from hospitals worldwide by a US company called Surgisphere, but a Guardian investigation has since revealed the database to be seriously flawed. The revelation, combined with concerns highlighted by scientists worldwide about the data, prompted the journal to retract the study. The Lancet, another leading medical journal, also published a study based on the Surgisphere database.
