International platform of registered systematic review and meta-analysis protocols
“Publication of a protocol for systematic review prior to knowledge of the available studies reduces the impact of some potential bias. Additionally, prospective protocol promotes transparency of methods and processes, and allows peer review of the planned methods.”
(Cochrane Handbook 2019)
“Systematic reviews and meta-analysis should build on a protocol that informs the planned methods, rationale, and hypothesis of the study.”
(PRISMA-P 2015)
