The constructed miRNA-disease network. The bipartite network was composed of miRNAs (triangles) and diseases (circles). A disease is linked by miRNA if the p-value is less than 0.05. Disease nodes are colored according to disease class information from GAD; diseases are classified into 18 categories. The size of a node is proportional to the degree of the node, whereas the thickness of an edge is proportional to the p-value; the smaller the p-value the thicker the edge (A). The top 10 largest degree miRNAs in the miRNA-disease network (B). The top 10 largest degree diseases in the miRNA-disease network (C). The diseases associated with only one miRNA in the miRNA-disease network.
