OSF Registries | Systematic Review assessing the citation advantage difference between Green and Gold Open Access

"Many analyses have looked at whether open access is more likely to elicit citations on journal articles than subscription based access is. A small number of systematic reviews have also been carried out in the topic, the most recent being by Langham-Putrow, A., Bakker, C., & Riegelman, A. (2021). The results of this systematic review were inconclusive due to many of the articles being removed from the analysis after being assessed as biased. However there was a suggestion that an open access citation advantage exists in subsets of data.

Most studies have primarily considered open access as a homogenous group, however there may be a difference in citation advantage between green (author deposited) open access and Gold (publisher enabled) open access. This difference is likely to be primarily due to issues around access and discoverability of open versions of articles. This systematic review will attempt to answer the question of whether there is a difference in citation advantage between green and gold open access...."
