Figure 7

Mapping of cocitation related to shock wave therapy. (a) Mapping of cocited references related to the field. (The 498 points with different colors represent the 435 cited references. The size of the points represents the citation frequency. A line between two points means that both were cited in one paper. A shorter line indicates a closer link between two papers. Points in the same color belong to the same research direction.) (b) Mapping of cocited journals related to the field. (The 825 points with different colors represent the 825 identified journals. The size of the points represents the citation frequency. A line between two points means that both were cited in one journal. A shorter line indicates a closer link between two journals. Points in the same color belong to the same research direction).
