“…Even when controlling for these factors, the size of the citation/altmetric advantage remains substantial: Fu and Hughey (2019) report that articles with a preprint received 1.36 times more citations and 1.49 times higher Altmetric Attention Scores than articles without a preprint, whilst Fraser et al (2020) report that articles with a preprint received 1.56 times more citations, 2.33 times more tweets, 1.55 times more blog mentions, 1.47 times more mainstream media mentions, 1.30 times more Wikipedia citations and 1.81 times more Mendeley reads than articles without a preprint. These findings of a “bioRxiv citation/altmetric advantage” are in agreement with findings based on similar studies conducted on arXiv (Davis & Fromerth, 2007; Larivière et al, 2014; Moed, 2007; Wang, Chen, et al, 2020; Wang, Glänzel, et al, 2020), and related studies that have investigated the more general Open Access (OA) citation advantage, finding that OA articles tend to be more strongly cited than non-OA articles (Gargouri et al, 2010; Archambault et al, 2016; Piwowar et al, 2018).…”
