Scientometric dynamics of scientific publications on gut microbiota and gluten: Overview, visualization, and mapping

Background: The aim of the study was to analyze the scientific production of gut microbiota and gluten by overview, visualization, and mapping. Methods: A descriptive study with a scientometric approach was carried out. A search of the Scopus database was performed on June 13, 2024, using a specific search formula and covering a search period from January 2019 to July 2024. Manuscripts were selected based on their relevance to the field under study, and 233 manuscripts were identified. The extracted data were analyzed using SciVal and Bibliometrix. Results: A total of 233 relevant manuscripts published between 2019 and 2024 were identified. The journal Nutrients was particularly prominent, contributing 28 articles and demonstrating high productivity. Alessio Fasano was recognized as the most influential author in this field. Most papers were ranked in the Q1 quartile, indicating their high quality. The principles of Bradford's and Lotka's laws were confirmed, with some sources and authors responsible for most of the papers. Italy was found to be leading in terms of international collaborations. These findings offer valuable insights into the scientific output of this field, highlighting key trends and identifying influential contributors. Conclusion: Trends in scientific output on gut microbiota and gluten were highlighted, including the journal Nutrients, the productivity of Fasano, and the international collaboration led by Italy. Bradford's and Lotka's laws provided valuable insight into the distribution of scientific output.
