Bibliometric study of placenta in pregnancy-induced hypertension

Abstract

Background: The placenta is a responsible organ for nourishing and protecting the fetus during pregnancy. It is a key limb for pregnancy evolution and fetal expansion that acts on maternal-fetal exchanges of gas and nutrients. Materials and Methods: This bibliometric analysis investigated the publications that were produced from 1977 to 2021 and indexed in PubMed database. The database was inspected for all documents related to placenta in pregnancy. About 298 documents were found and examined in database. The VOSviewer software was used to imagine the co-occurrence arrangement. Results: The analysis found the greatest publications resulted out from the “USA” (n = 282), “China” (n = 185), and “Australia” (n = 153). In addition, the results found that most of the publications are journal article (n = 222). “Pregnancy Hypertension” supplied the majority of documents. Almost all documents were produced in the last decade (2011–2021). The study found the most relevant affiliations where University of Melbourne ranked first (n = 80), King's College London ranked second (n = 54), and University of Mississippi Medical Center ranked third (n = 50). The study found Hannan NJ (n = 10, TC = 1.22) as the most productive author in the field. The co-occurrence scrutiny confirmed that the study formed five clusters. The study found that “pregnancy,” “female,” “human,” “pre-eclampsia,” and “adult” are the most useful keywords on the topic. Conclusion: Assessment of placenta is an enormously important interpreter, which helps to progress the result of pregnancy. This bibliometric study illustrates the overall research scenery, trends, growth, impact, and collaborative work among scholars in the field of placenta in pregnancy-induced hypertension.
