Peer review potentially improves reporting and reduces errors, although its actual impact is not known. The objective of this scoping review was to synthesize evidence comparing preprints in the health areas to their peer-reviewed versions and assess preprint publication rates.<h4>Methods</h4>We searched Embase, Medline OVID, Scopus, and Web of Science from inception to July 2024 for studies comparing preprints with their peer-reviewed versions and/or investigating preprint publication rates.
