Implementing GRADE in systematic reviews that adhere to JBI methodological conduct.

GRADE is a methodological approach used to establish certainty in a body of evidence and is now widely adopted among the evidence synthesis and guideline development community. JBI is an international evidence-based health care organization that provides guidance for a range of evidence synthesis approaches. The GRADE approach is currently endorsed for use in a subset of JBI systematic reviews; however, there is some uncertainty regarding when (and how) GRADE may be implemented in reviews that follow JBI methodology.
