Global research on NK cells in miscarriage: a bibliometric study
Abstract
BackgroundThis study aimed to assess the evolution, trends, and research hotspots of publications related to natural killer (NK) cells and miscarriage.MethodsThe literature on NK cells and miscarriage was retrieved from the Web of Science Core Collection. VOSviewer and CiteSpace were used to analyze the publication years, countries, institutions, journals, highly cited authors, categories, and citation bursts of keywords.ResultsA total of 1,275 articles were analyzed. The annual publication outputs showed steady growth, with the majority of publications in 2020 and citations in 2022. The number of publications in this field fluctuated from 1981 to 2023, with a slight downward trend observed. However, the number of citations increased steadily until 2023, followed by a minor decline. The United States contributed the highest number of publications and had the highest h-index. The American Journal of Reproductive Immunology ranked first in terms of number of publications and h-index. Reproductive biology, immunology, and obstetrics and gynecology were the most representative disciplines. Kwak-kim J, Chaouat G, and Croy BA were the top three most productive authors in the field. Keyword burst analysis demonstrated that the immune system and cytotoxicity receptors were current research hotspots.ConclusionThis is the first bibliometric study to comprehensively summarize trends and advances in the study of NK cells in miscarriage. This information highlights the recent research frontiers and emerging directions and provides a reference for subsequent research in the future.
