Advances and global trends of precancerous lesions of gastric cancer: A bibliometric analysis

Figure 1  Flowchart illustrating the literature inclusion, exclusion, and analysis processes.

Figure 2 Quantitative analysis of publication and the co-authorship map of countries/regions and institutions. A: Annual number of publications for precancerous lesions of gastric cancer; B: Annual number of publications in the top 5 countries/regions; C: Co-authorship map of countries/regions. Each node represents a country/region, with the node size corresponding to the number of publications from that location. The connections between nodes represent collaborations, while the intensity of the color reflects the total link strength; D: Co-authorship map of institutions. The nodes in the network map represent institutions, and the size of each node is proportional to the number of publications. The thickness of the connecting lines between nodes indicates the strength of the co-authorship relationships, with colors indicating different clusters.

Figure 3 Co-authorship map of authors, highly cited publications, and analysis of keywords. A: Co-authorship map of authors; B: Changes in citation volume of the top 10 highly cited publications over time; C: Co-occurrence map of keywords. In the network map, the nodes represent keywords, with node size proportional to the frequency of each keyword. The thickness of the connecting lines between nodes indicates the strength of the co-authorship relationships, while colors represent different clusters.
