It is recommended that you register your systematic review protocol prior to conducting your review. This will improve transparency and reproducibility, but will also ensure that other research teams do not duplicate efforts. If you are working with the Cochrane or Campbell Collaborations, you will publish your protocol with those organizations. If you are working independently, consider registration with:
PROSPERO: An international database of prospectively registered systematic reviews in health and social care. Key features from the review protocol are recorded and maintained as a permanent record.
Open Science Framework: An open source web application that connects and supports the research workflow. Researchers use the OSF to collaborate, document, archive, share, and register research projects, materials, and data. OSF can be used to pre-register a systematic review protocol and to share documents such as a Zotero library, search strategies, and data extraction forms.
