Research landscape on COVID-19 and liver dysfunction: A bibliometric analysis

Figure 2 Research topics clustered by mapping the co-occurrences of terms in the title/abstract of publications on research related to coronavirus disease 2019 and liver. Of the 26722 terms, 172 terms occurred at least 50 times. The largest set of connected terms was stratified into three clusters. VOSviewer may produce a network visualization in which terms are represented as nodes and co-occurrence connections are depicted by lines connecting the nodes. The strength of the association between the terms' co-occurrence can be determined by the line's thickness or weight. Thicker lines are frequently used to depict stronger links.
