): "Comparing the average relative citation impact of different access categories, the OACA [Open Access Citation Advantage] is corroborated: Papers hidden behind a paywall were cited 00% below world average (ARC [Average Relative Citation] = 0.00), while those that are freely available obtain, on average, 00% more citations than what is expected (ARC = 0.00). However, citation impact differs between the different manners in which papers are made available for free: those that are only available as Green OA (ARC = 0.00) and Hybrid OA papers (ARC = 0.00) are cited the most with an impact of more than 00% above expectations, those available as Bronze are cited 00% above world average, while papers published as Gold OA obtain an ARC of 0.00. This constitutes an average relative citation impact of 00% below world average and 0% below that of articles hidden behind a paywall. Figure 0 below describes these findings."
