Differential gene expression analysis of the lungs of COVID-19 patients compared to controls. (A) Individuals utilized in the analysis grouped according to their comorbidities. The x-axis shows the body mass index (BMI) for each individual. Individuals with a BMI above 30 (grey dashed line) were considered obese. (B) Number of differentially expressed genes (DEGs) of each COVID-19 patient group compared to control. The Venn diagram shows the number of upregulated genes (red) and down-regulated genes (blue) that were shared or unique to each group. (C) DEGs with opposite expression among the groups.
