"Clear reporting of a systematic review allows readers to evaluate the rigour of the methods applied, and to interpret the findings appropriately. Transparency can facilitate attempts to verify or reproduce the results, and make the review more usable for health care decision makers. ... Review authors should ensure that reporting of objectives, important outcomes, results, caveats and conclusions is consistent across the main text, the abstract, and any other summary versions of the review (e.g. plain language summary)."
