Heat map and Violin plots of pathways in patients with mild, moderate or severe disease. Pathways are: a) Complement and coagulation cascades, b) Cytokine-cytokine receptor interaction, c) JAK-STAT signaling pathway, d) TGF-beta signalling, e) Platelets activation, and f) Ribosome. Heat map depicts the log2 fold change of differentially expressed gene (DEGs) of COVID-19 patients compared with controls. Genes included have a log2 fold change of more than 1 and a p-adjusted value of <0.05. For every gene in a given pathway, the average counts per million (CPM) was calculated in cases with mild (n = 37), moderate (n = 10) and severe (n = 3) disease, and these CPM values (dark dots) were plotted (Violin plots) indicating median and quartiles as well as minima and maxima bounds. *Expression of ACE2 and TMPRSS2.
