Bibliometric analysis and evaluation of publications on non- from 1993 to 2023.

A bibliometric analysis and evaluation of research on non- species (NHPHs) is essential to determining future research directions. A comprehensive search was carried out using predetermined search terms within the Web of Science Core Collection (WoSCC) to gather publications spanning from 1993 to 2023. VOSviewer and Citespace were employed for data analysis and visualization. 308 publications on NHPHs were included. Among these, gastric NHPHs received more publications and attention compared with enterohepatic NHPHs. Key findings included the identification of most productive countries, institutions, journals, authors, keywords, research trends and notable perspectives in the field. The article guides further research and clinical applications on NHPHs.
