Literature curation of genes associated with key COVID-19 comorbidities. A, Text-mining of 8727 abstracts identified 6 relevant disease medical subject heading (MeSH) terms associated with a total of 804 genes. The number of genes associated with each disease MeSH term in at least 4 abstracts is shown in the pie chart. B, The knowledge-based network of COVID-19 comorbidities. The network shows the diseases (red nodes) and genes (purple nodes) from (A). The edges represent an association between a disease and a gene. The size of the nodes is proportional to its degree. C, Genes associated with 4 or more COVID-19 comorbidities.
