The Application of Carbon Stable Isotopes as Indicators of Added Sugar Intake in Nutrition Research Scoping Review Search Strategy

To identify studies to include or consider for this scoping review, the review team worked with a librarian (VAN) to develop detailed search strategies for each database. The PRISMA-S extension was followed for search reporting. The librarian (VAN) developed the search for PubMed (NLM) and translated the search for every database searched. The PubMed (NLM) search strategy was reviewed by the research team to check for accuracy and term relevancy, and all final searches were peer-reviewed by another medical librarian (TN) following the PRESS checklist. The databases included in this search are PubMed (NLM), Embase (Elsevier), Cochrane Central (Wiley), Web of Science (Clarivate Analytics), CINAHL (EBSCOhost), APA PsycInfo (EBSCOhost), and SPORTDiscus with Full Text (EBSCOhost) using a combination of keywords and subject headings. A gray literature search included 2 clinical trials registries, clinicaltrials.gov and the World Health Organization International Clinical Trials Registry Platform (https://trialsearch.who.int/). There were no limits to the search. All final searches were performed on July 20, 2022 by the librarian and were fully reported (VAN). The full search strategies as reported by the librarian are provided. A summary of the search results from databases: PubMed (NLM) from inception to 7/20/2022 (2,501 Results) Embase (Elsevier) from inception to 7/20/2022 (1,264 Results) Cochrane Central (Wiley) from inception to 7/20/2022 (309 Results) Web of Science (Clarivate Analytics) from inception to 7/20/2022 (813 Results) CINAHL (EBSCOhost) from inception to 7/20/2022 (247 Results) APA PsycInfo (EBSCOhost) from inception to 7/20/2022 (25 Results) SPORTDiscus with Full Text (EBSCOhost) from inception to 7/20/2022 (176 Results) The search resulted in 5,335 studies from databases and 59 from registers. A total of 1,007 duplicate studies were found and omitted by the librarian (VAN) using the EndNote 20 duplicate identification strategy. This resulted in 4,387 records to screen from databases and registers and 0 records to screen from other methods, resulting in a total of 4,387 records. Studies were screened by title and abstract by two blinded and independent reviewers. If a tiebreaker was needed, a third reviewer was called in. This process was repeated for full text article screening and article selection.
