Are OA papers more highly-cited?

Results and methodological reflections of an application of multiple measures to an analysis by WoS subject areas. Scientometrics 126, 459–484 (2021). https://doi.org/10.1007/s11192-020-03734-9 (Key results: “ We found that OA journal articles experience a citation advantage in very few subject areas and, in most of these subject areas, the citation advantage was found on only a single measure of citation advantage, namely whether the article was cited at all. Our results lead us to conclude that access status accounts for little of the variability in the number of citations an article accumulates. “)

(Key results: "We have found a positive effect for OA journals in general. However, the effect is more pronounced in journals that are published by the Big Five publishers, and in journals in Biology, Medicine and Science. More surprisingly, the OA effect is more pronounced in lower ranked journals than in high-ranking journals, suggesting a “long tail” effect")

(Key results: “Even though effects found here are more modest than reported elsewhere, given the conservative treatments of the data and when viewed in conjunction with other OACA studies already done, the results lend support to the existence of a real, measurable, open access citation advantage with a lower bound of approximately 20%.”)
