PPI network diagram and selection of hub genes. A Protein–protein interactions (PPIs) network for identified common feature genes that are shared by two diseases (COVID-19 and OSA). Purple nodes indicate genes with the top 10 interaction degree in the network. Nodes in yellow color indicate common feature genes and edges specify the interconnection in the middle of two genes. B Detection of hub genes from the PPIs network of common feature genes. A redder color means a higher degree of interaction
