Register the review protocol

In order to assist others, you should register your review protocol in the registries described above. You can do this in PROSPERO, or with an appropriate review group in Cochrane or the Campbell Collaboration (which provide quality assurance, publishing, translation and other benefits for eligible and accepted titles and protocols). The protocol should be prepared and published in advance of the conduct of the review, to reduce the risk of bias  and to clarify plans (for example, identifying the main outcomes of interest). Protocols should be freely accessible to readers as a key quality measure. Cochrane reviews protocols are open access and it is also possible to publish protocols in journals such as Systematic Reviews or on the Open Science Framework.
