Why should complete a protocol?
Resources to help authors prepare a protocol for a systematic or scoping review:
After you write the protocol, you should register it with a review registry. There are numerous review registries available, such as PROSPERO or OSF. Registration is free and open to anyone undertaking systematic reviews. Some journals also publish systematic review protocols.
Scoping reviews may not be registered with PROSPERO. Currently, they can be registered with the Open Science Framework or Figshare.
OSF can be used to register a systematic or scoping review protocol and to share documents such as the full protocol, a citation management library, search strategies, and data extraction forms. Protocols are not reviewed by an editorial board before they are accepted on OSF.
