Figure 5 Co-citation map (timeline view) of references from publications on pain in the elderly. The size of the nodes reflects the number of publications or frequency; the larger the node, the higher the number of publications or frequency. The different colors within the nodes represent different times, the connection lines between the nodes reflect the relationship between the co-operation or co-citation, and the color of the line reflects the years when the co-operation or co-citation first appeared. Nodes with a larger centrality are more likely to become the key nodes in the network and are represented by purple on the node ring in the knowledge network map.
