Fig. 2From: Large-scale mining disease comorbidity relationships from post-market drug adverse events surveillance dataCharacteristics of disease comorbidity network. a Visualization of DCN. Diseases are represented as nodes and the size of each node is proportional to the degree of that node. Node color represents disorder class (SOC in MedDRA) to which it belongs. Edges between nodes are represented as the co-occurrence of diseases. b Basic network property of DCN. c Distribution of disease comorbidity in DCNBack to article page
