    Abstract

    Purpose: The cervix undergoes a dynamic remodeling process throughout pregnancy. Appropriate timing of cervical remodeling is essential in maintaining the fetus inside the uterus and ensuring cervical dilatation for safe delivery of the fetus at term. This study aims to determine the characteristics and trends of published articles in the field of cervical remodeling during pregnancy through a bibliometric analysis. Materials and methods: A systematic review of the literature on cervical remodeling during pregnancy was performed on using the Scopus database from inception to 2020. The following information was obtained for each article: authors, year of publication, title, journal, institution, country, title, keywords, citation frequency, and relative citation ratio. The visualization of collaboration networks of countries and keywords related to cervical remodeling during pregnancy was conducted using VOSviewer software. Results: A total of 1979 bibliographic records were obtained from Scopus database. The number of publications increased in the 1980s and peaked in 2010. A total of 80 countries produced research in cervical remodeling during pregnancy. The USA contributed the greatest number of publications (n= 541), total citations (n= 11,971), and number of international collaborations (n= 28 countries). The American Journal of Obstetrics and Gynecology, Obstetrics and Gynecology, and BJOG: An International Journal of Obstetrics and Gynaecology are the top three contributors in this field in terms of number of publications and total citations. The Karolinska Institutet produced the greatest number of publications while UT Southwestern Medical Center was the most cited institution in this field. The topics of the top cited articles were studies regarding the role of collagen degradation in cervical remodeling during pregnancy; dynamics, anatomy, and physiology of cervical remodeling; and the use of misoprostol for cervical ripening and labor induction. Conclusions: Our bibliometric analysis shows the trends and development, scientific impact, and collaboration in the field of cervical remodeling research. These results show the important discoveries in the past and provided new avenues for scientific and clinical investigations in the field.
