If you are planning to write a systematic review, scoping review, or similar type of review, you may wish to register a review protocol towards the beginning of the process. Publishing a protocol is not mandatory if you are writing a review, but it is increasingly considered best practice.
Registering a protocol can help improve transparency and reduce bias in the conduct of reviews. It also allows researchers to discover which reviews are currently in progress, reducing the likelihood of duplication of effort.
Many journal publishers now require a protocol to be registered at the outset of a review.
Registration sites may provide guidance on what to include in a protocol. General guidance on what to include is also available in the PRISMA-P checklist.
You may wish to consider publishing or registering a protocol on one of the sites below.

They differ from traditional literature reviews particularly in the following elements of conduct and reporting.
