Fig. 4.

Network of research fields among One Health Publications. Each publication was assigned at least one ASJC research field by Scopus. The connection between two fields was counted as one path if a study covered these two fields. If the study involved three fields, it was counted as having three connecting paths. Thus, a network contains all the research fields identified and is formed by the presence of paths connecting the One Health publications involved. The research fields in this figure are presented according to their subject areas, which include Health Science, Life Science, Social Science & Humanities and Physical Sciences presented with one in each of the four corners of the figure playing the role of areas of gravitation. To ensure all research fields were clearly shown in this figure, the location of each point was adjusted manually. The distances across each point have no special meaning. Paths between two fields with less than 20 publications are not shown.
