Research status and hotspots in transjugular intrahepatic portosystemic shunts based on CiteSpace bibliometric analysis

Figure 6 Co-cited reference network. Each node represents a co-cited reference, and the purple outer circle of the node indicates a high betweenness centrality. The size of the node is proportional to the number of co-citations. The connection between nodes represents the co-citation relationship, and the color of the connection represents the time of the first co-citation. The thicker the connection is, the stronger the link between co-citations.
