Results of Open Access RTC Robust at 3 Years
23 November 2010
All of the articles in our study have now aged 3-years and we report that our initial findings were robust: articles receiving the open access treatment received more article downloads but no more citations .
Article Downloads During the first year of publication, open access articles received more than double the number of full-text downloads (119%, 95% C.I. 100% - 140%) and 61% more PDF downloads (95% C.I. 48% - 74%) from a third more unique visitors (32%, 95% C.I. 24% - 41%). Abstract views were reduced by nearly a third (-29%, 95% C.I. -34% - -24%) signaling a reader preference for the full article when available.
Article Citations Thirty-six months after publication, open access treatment articles were cited no more frequently than articles in the control group. Open access articles received, on average, 10.6 citations (95% C.I. 9.2 -12.0) compared to 10.7 (95% C.I. 9.6 - 11.8) for the control group. No significant citation differences were detected at 12, 18, 24 and 30 months after publication.
