Research status and hotspots of tight junctions and colorectal cancer: A bibliometric and visualization analysis

Figure 5 Visualization of keywords related to tight junctions and colorectal cancer research from 2001 to 2023. A: The cooperation network of keywords in the field. Dots represent keywords, with larger dots indicating a greater frequency of keywords. Clusters are marked using different colors, and links represent co-occurrence between keywords; B: The density of keywords in the field; C: Temporal view of keyword co-occurrence analysis (the node color represents the average year of keyword occurrence); D: Keyword clustering analysis in this field. Different colors represent different clusters. Each point represents a keyword, and the number on the node represents the cluster to which the keyword belongs. The different patterns represented a cluster. Tag# was allocated to clusters; the smaller the count was, the greater the number of keywords in the cluster.
