PPI network analysis of COVID-19-related KD hub genes. (a) PPI network of 26 hub genes. (b) Fifteen genes in the most representative module screened by the ‘MCODE’ plug-in. (c) Common hub genes identified from four algorithms of cytoHubba(MCC, EPC, Degree and MNC). (d) Network of the nine common hub genes. MCC: Maximal Clique Centrality, EPC: Edge Percolated Component, MNC: Maximum Neighborhood Component
