NAFLD PPI network. (A) SS PPI network; (B) NASH PPI network; (C) NASH cirrhosis PPI network. Yellow nodes represent the genes of module 1, pink nodes represent the genes of module 2, blue nodes represent hub genes, and red nodes represent the intersection of module genes and hub genes. The size of nodes is positively correlated with the degree value of nodes. NAFLD = nonalcoholic fatty liver disease, NASH = nonalcoholic steatohepatitis, PPI = protein–protein interaction.
