A total of 1,003 English articles and reviews published between 2015 and 2025 were retrieved from the WOSCC, Scopus, and PubMed databases according to the search strategy. After merging and deduplicating based on DOI, the collection was reduced to 489 publications. Manual screening of titles and abstracts excluded irrelevant studies, yielding 340 publications for final inclusion. Bibliometric analysis across seven domains was performed using Bibliometrix, CiteSpace, and VOSviewer. DOI: Digital object identifier; WOSCC: Web of Science Core Collection.
