 This meta-research study will examine the reporting completeness of diet or nutrition-related randomized control trial, RCT, protocols published in six selected databases from 2012 to 2022. Two reviews will independently screen the titles and abstracts of records yielded by the search in PubMed, M-Base, SINNL, Web of Science, PSYC-INFO, and Global Health. Four texts will then be read to confirm protocol eligibility. A randomly selected sample of protocols will be assessed for reporting completeness against the spirit and tidier statements. The main reporting limitations of these protocols will also be identified. The results will be disseminated through journals and conferences targeting stakeholders involved in nutrition research.
