Lancet leapfrogs NEJM as Covid-19 drives surging citation numbers for medical journals
The Lancet has overtaken the New England Journal of Medicine in the latest data on impact, marking the first time that the NEJM has not held the top spot for general medicine.
The annual Journal Citation Reports (JCR) from analytics company Clarivate calculates impact factor, which is a measure of how many times the papers a journal publishes are cited by other work. (Research Professional News is an editorially independent part of Ex Libris, which is owned by Clarivate.)
