Systematic reviews should set clear questions, the answers to which will provide meaningful information that can be used to guide decision-making. These should be stated clearly and precisely in the protocol.
Questions may be extremely specific or very broad, although if broad, it may be more appropriate to break this down into a series of related more specific questions.
Aids to formulate clear question(s):

Prospectively registering a protocol of a systematic review reduces duplication of effort, research waste, and promotes accountability:
Publication of a protocol for a review that is written without knowledge of the available studies reduces the impact of review authors’ biases, promotes transparency of methods and processes, reduces the potential for duplication, allows peer review of the planned methods before they have been completed, and offers an opportunity for the review team to plan resources and logistics for undertaking the review itself.”

Depending on the type of (systematic) review, there are different places where and how to register a protocol:
|Prospero (the International Prospective Register of Systematic Reviews)||Systematic reviews, rapid reviews, umbrella reviews||Help with registration|
|Cochrane Reviews||A Cochrane Protocol is a description of the proposed approach for a Cochrane Review, outlining the question and the methods for assessing and analysing studies. Cochrane Reviews and Protocols are prepared by author teams, who may be supported by a topic-based Cochrane Review Group.||Template for protocols|
|Journal Systematic Reviews||The journal publishes high quality systematic review products including systematic review protocols.
Systematic reviews related to a very broad definition of health, rapid reviews, updates of already completed systematic reviews, and methods research related to the science of systematic reviews, such as decision modelling.
