Fig. 3From: Machine learning analysis of gene expression profile reveals a novel diagnostic signature for osteoporosisThe construction of PPI network. a The PPI network. Each dot represents a node. The more lines connected to the dot, the higher the degree of this node, which means the more important the genes on this node may be in the network. b The top 50 genes with high degree in PPI network were screened based on MNC algorithm. The darker the red color was, the higher the degree wasBack to article page
