C2's Register of Interventions and Policy Evaluations
(C2-RIPE)
Through C2-RIPE, researchers, policymakers, practitioners, and the public can access Campbell Reviews and review-related documents at each stage of their development. Online access to these documents is free of charge. We encourage and invite people to develop systematic reviews that can eventually be entered into C2 RIPE.
Readers of C2 reviews, including authors of studies under review, may contribute facts and analyses pertinent to the review by corresponding with the review authors and relevant coordinating group chairperson(s) to provide the additional information. (C2 asks writers to submit a declaration of possible conflict of interest, just as C2 asks authors of reviews to submit this declaration.)
The C2-RIPE database contains approved Campbell titles, protocols. completed reviews, and abstracts or one-page plain English summaries. Registered titles with an approved protocol, review and abstract, will have a “view documents” hypertext link. If a registered title does not have a “view documents” link, then approval of the protocol is pending.
Ultimately, C2-RIPE permits anyone to critique a protocol or review, make suggestions about for improvement, and identify parallel review efforts so as to avoid duplication. This information will be subject to editorial review and will be posted on the C2 web site if it adds factual information to update or correct errors in a review. The additional information will be posted under the authors’ names.
