Research trends of ferroptosis and pyroptosis in depression: A bibliometric analysis

Figure 3 Geographic distribution and international collaboration networks of countries/regions in ferroptosis- and pyroptosis-related depression research. A: Geographic distribution of publications on ferroptosis in depression; B: Geographic distribution of publications on pyroptosis in depression; C: International collaboration network of countries/regions in ferroptosis in depression; D: International collaboration network of countries/regions in pyroptosis in depression. In these visual maps, each node represents a country, and the links between countries represent collaborative relationships. The size of each node is proportional to the total number of publications. Red nodes indicate greater collaboration between a country and other countries, while thicker connecting lines between nodes indicate closer collaboration between the 2 countries.
