Preprint servers in lipidology: current status and future role.

PURPOSE OF REVIEW

Preprinting, or the sharing of non-peer reviewed, unpublished scholarly manuscripts, has exploded in all fields of science and medicine over the past 5 years. We searched the literature and evaluated the posting and uptake of preprint publications in the field of lipidology in bioRxiv and medRxiv servers. We also contacted the editorial offices of 20 journals that publish original research in lipidology to gauge their policies on preprints.

RECENT FINDINGS

All 20 journals contacted indicated that they accepted preprints. As of 31 May 2021, 473 and 231 preprints in lipidology had been submitted to bioRxiv and medRxiv, respectively. About half of all lipidology preprints were related to cardiovascular, cardiometabolic, and/or metabolic diseases (CVMD) and their risk factors, but at least 12 other disease categories were also represented. 16.9% and 1.08% of medRxiv and bioRxiv preprints, respectively, were related to coronavirus disease 2019 (COVID-19).

SUMMARY

All identified journals accept lipidology themed preprints for submission, removing any barriers authors may have had regarding preprinting. Based on growing experience with preprinting, this trend should encourage increased community feedback and facilitate higher quality lipidology research in the future.
