Summary
This open access paper (published in November 2022) and the research it reports looked at the degree to which the scientific details of preprint papers were altered when they appeared in a peer-reviewed journal. This highlights that the value of rapid publication and open/immediate peer review does not entail a loss of quality and vigour. It does indicate that preprints serve a valuable role during pandemics and other global medical emergencies. Perhaps, certain grant funding bodies need to take a more nuanced approach to preprints.
