Immune cells in metabolic associated fatty liver disease: Global trends and hotspots (2004-2024)

Figure 5 Co-citation clustering and citation burst analysis. A: Cluster analysis map of co-cited references. The parameters in CiteSpace were set as follows: Time slicing (2004-2024), one year per slice, and selection criterion (k = 4). The size of the superimposed rings (i.e., the cumulative size of the rings on the timeline) is proportional to the number of co-citations. Purple indicates relatively early citation years, while yellow indicates more recent citation years. Overlapping colors suggest that the article was cited in each corresponding year. Lines between circles represent co-citation relationships. Nodes marked in magenta are key nodes with centrality greater than 0.1; B: Citation burst analysis map. A citation burst refers to a significant increase in the number of citations a particular article receives within a specific time frame. The red areas in the graph indicate the periods during which the citations of each article surged.
