The Campbell Standards are based on the MECCIR and the PRISMA-2020 reporting standards and include seven main sections with 35 items. All the items provided in the checklist are to be interpreted by authors as mandatory for a protocol, review, or update to be published in the Campbell Systematic Reviews journal. It is important to note that guidance related to analyzed data might not be relevant for protocols or reviews without meta-analysis or reviews with qualitative syntheses.
Authors must submit the checklist affirming adherence to the Campbell Standards to their respective editors when submitting the protocol or review for editorial processing.
The Campbell Standards is a living document and will be updated periodically considering new evidence.
Authors can still download and review the archived MECCIR standards for more detailed guidance to support review production.
