Bibliometric analysis and evaluation of publications on non-Helicobacter pylori helicobacters from 1993 to 2023

Aim: A bibliometric analysis and evaluation of research on non-Helicobacter pylori Helicobacter species (NHPHs) is essential to determining future research directions. Materials & methods: 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. Results: 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. Conclusion: The article guides further research and clinical applications on NHPHs. Previous global research trends in non-Helicobacter pylori Helicobacter species (NHPHs) have focused on population studies and clinical implications. The future research direction of NHPHs lies in exploring the correlation between its biological characteristics and gastrointestinal diseases. The bibliometric analysis of this study may provide a reference for researchers in the same field to add to the body of knowledge a summative review of research in the field of NHPHs and an independent insight into the prediction of future research trends.
