Abstract´╝Ü Objective:To analyze the research status of umbrella review by bibliometric methods.Methods:The citation search was performed via Web of Science Core Collection database to obtain studies on umbrella review from inception to December 31, 2021. VOSviewer1.6.16 was used to extract the included authors, countries, institutions and keywords, and generate the cooperative network graph of high-productivity authors, countries, institutions, and clustering graph of high-frequency keywords. CiteSpace5.7.R5W was used to detect burst terms.Results:A total of 755 articles or reviews were included. The quantity of studies had been increasing over time. The United Kingdom was the country with the most published papers (297), and the University of College London was the institution with the most published papers (77). A total of 3 863 authors participated in the umbrella review research, of which Solmi M had the largest number of papers with 28 papers published. The main authors formed three groups, with little cooperation between the groups. Research hotspots focused on chronic diseases such as cardiovascular disease, diabetes, cancer, mental health and its health management. Besides, diabetes, heart failure and Mediterranean diet were the frontier fields.Conclusions:Umbrella review is in the development stage, and the amount of studies is increasing. The United Kingdom is in a leading position in this field. The members of each team work closely together, but there is a lack of cross-team cooperation. Chronic diseases and their management are currently research hotspots and key research contents.
