There are two options for inclusion of evidence sources within JBI systematic reviews of textual evidence. The first option is to clearly indicate in the protocol which types of text will be included in the review, and then only include those textual evidence types during selection. This approach is transparent in that you are only including textual evidence that is either narrative, expert opinion or policy. The second option is to consider the question you are trying to answer and include evidence from all three textual evidence types. This will depend on the question, as there may not be all three types of evidence available. Where feasible, JBI prefers this option, as it is the most inclusive approach. If reviewers have decided to combine the results from all three types of textual evidence, then clear reporting must be provided regarding the inclusion process. Whichever option is taken, authors need to justify their decision.
