Figure 3.
Cumulative number of review and research articles published in series or by publishers explicitly or implicitly adopting non-selective review. Scientific Reports: data calculated from year by year lists of papers at (Scientific Reports, 2015); Frontiers—internal data; BMC: results from Scopus search for “articles,” “review,” and “articles in press” (February 18, 2015); Hindawi—results from search for “research articles” and “review articles” at http://www.hindawi.com/search/ (February 18, 2015). PLOS ONR—results from search for “research article” and “systematic review” at http://www.plosone.org/search/advanced?noSearchFlag=true&query=&filterJournals=PLoSONE (February 18, 2015). Data for BMC series and Hindawi includes some journals that use selective review. The numbers of papers published by these journals is too small to significantly affect the results.
