This website analyzes all publications posted on bioRxiv.org and medRxiv.org related to COVID-19 SARS-CoV-2. However, there is a lag between our analysis and the latest preprints posted there.

The goal of our checks is to help the peer-review process of these articles. Coronavirus has put tremendous strain on the peer review system where thousands of preprints are waiting to be peer-reviewed by experts (see here and here). We hope to help by detecting potential issues.

If you believe that your preprint has been incorrectly listed on this website, please send an email to deacuna at syr.edu with the DOI information.
