Authors collaboration analysis. A Visualization map of the top 7 author collaborations related to m6A methylation in viral infection. Each node with colorful annual rings represents an author. The size of the nodes matches the publications of the author. The nodes circled in purple represent greater centrality. The separate areas made up of nodes and links represent the author collaborative relationships. B Co-occurrence network analysis of institutions reveals collaborative relationships. The map, with a network density of 0.0232, consists of 236 nodes and 642 links. The largest node is the Chinese Academy of Sciences, circled in purple, with a centrality of 0.12, indicating that it plays a critical role in this field. Most institutions have collaborated, such as Duke University, Zhejiang University, University of California San Diego, and The University of Chicago (left). To explore the research topics between institutions, keywords were clustered using the log-likelihood ratio test (LLR), with ‘m6A’ as the keyword being the largest cluster (right)
