Abstract: Objective：This study aims to explore the current status and hot topics of Network Meta-analysis through bibliometric analysis. Methods： In this paper， three global databases including Pub Med， EMBASE.com and Cochrane library were used as data sources to retrieve literatures related to Network Meta-analysis. In addition， VOSviewer， Cite Space and R software are used to analyze the publication time， country， institution and author distribution， hot topics and cutting-edge trends of included studies. Results： A total of 5 689 literatures were included in the visualization analysis， and the results showed that the Network Meta-analysis showed a steady increase trend in the number of publications from 2017 to 2022. The authors included 25 736 authors from 5 581 institutions in 104 countries， among which the top 3 countries were China， the United States and the United Kingdom， and the institutions were the University of Toronto， McMaster University and Sichuan University， and the authors were Tu， YK， Salanti， G and Tian， JH. The 47 authors with 15 or more publications formed seven groups， and the intensity of cooperation between the groups varied. The literature is published in 1 343 journals， the top 3 journals are Medicine， BMJ Open and Frontiers in Pharmacology. The 66 keywords with more than 60 occurrences formed 4 clusters. Conclusion： The number of Network Meta-analysis shows an increasing trend. The strength of cooperation among the groups involved in the mesh Meta-analysis is different， which is mainly manifested in close internal cooperation and weak cooperation among groups. Therefore， it is necessary to strengthen the cooperation among different groups. The research topics of Network Meta-analysis mainly involved the efficacy of interventions on disease and the methods and software of NMA.
