      Abstract

      Objectives

      To examine the prevalence of presumed predatory publications in Cochrane reviews, which are considered the gold standard.

      Study Design and Setting

      We selected two Cochrane networks with broad scope: the Musculoskeletal, Oral, Skin and Sensory Network and the Public Health and Health Systems Network. From reviews produced by all review groups in those networks in 2018 and 2019, we extracted included study citations published after 2000. For each citation, we assessed the journal and publisher using an algorithmic process based on characteristics known to be common among predatory publishers. Knowing that predatory status can be fluid and subjective, we scored citations on a spectrum from “reputable” to “presumed predatory” based on publication characteristics available at the time of assessment.

      Results

      We assessed 6,750 citations from 300 reviews. Of these citations, 5,734 were published by entities widely accepted as reputable, leaving 1,591 for further assessment. We flagged 55 citations as concerning.

      Conclusion

      Cochrane reviews across diverse topic areas included studies from flagged publishers, although this number is small. Because of this, there is potential for studies from predatory journals to influence the conclusions of systematic reviews. Researchers should stay aware of this potential threat to the quality of reviews.

          Predatory journals and publishers are a well described and pervasive problem in research across the globe. Although their characteristics are often debated, an international consensus definition has described these journals and publishers as “entities that prioritize self-interest at the expense of scholarship and are characterized by false or misleading information, deviation from best editorial and publication practices, a lack of transparency, and/or the use of aggressive and indiscriminate solicitation practices [1].” These journals exist primarily to exploit the open access system of publication that has been adopted by the biomedical research community–they collect article processing charges while failing to deliver services provided by legitimate journals (e.g., editorial oversight, copyediting, arranging peer review, indexing in reputable sources).
