Description
Summary:Problem A comprehensive analysis was conducted to explore the scientific output on immune‐related recurrent pregnancy loss (RPL) and its key aspects. Despite the lack of clear explanations for most RPL cases, immune factors were found to play a significant role. Method of Study The study utilized a bibliometric approach, searching the Web of Science Core Collection database for relevant literature published between 2004 and 2023. Results The collected dataset consisted of 2228 articles and reviews, revealing a consistent increase in publications and citations over the past two decades. The analysis identified the United States and China as the most productive countries in terms of RPL research. Among the institutions, Fudan University in China emerged as the top contributor, followed by Shanghai Jiaotong University. Kwak‐kim J was the most prolific author, while Christiansen Ob had the highest number of co‐citations. The top 25 co‐cited references on diagnosis, treatment, and mechanisms formed the foundation of knowledge in this field. By examining keyword co‐occurrence and co‐citations, the study found that antiphospholipid syndrome and natural killer cells were the primary areas of focus in immune‐related RPL research. Additionally, three emerging hotspots were identified: chronic endometritis, inflammation, and decidual macrophages. These aspects demonstrated increasing interest and research activity within the field of immune‐related RPL. Conclusions Overall, this comprehensive bibliometric analysis provided valuable insights into the patterns, frontiers, and focal points of global scientific output related to immune‐related RPL.
