From the Article

Preprints are versions of articles that are made publicly available prior to peer-reviewed publication, are widely used in physical sciences,1 and are now emerging in life sciences. Preprints provide immediate access to new information; however, articles not formally peer reviewed may contain errors in methods, results, or interpretation.

We also assessed whether Altmetric scores and citations of published articles correlated with prior preprint posting.
