Cytokine comparison COVID-19 vs. CAP (A) The unsupervised heatmap model where COVID-19 and CAP patients were divided into three subpopulations using an unsupervised model, according to their cytokine levels (B). This volcano plot represents cytokines with a higher P -value and delta value in red, a higher P-value and lower delta value in blue, and non-significant in grey. FGF-2 basic fibroblast growth factor, GM-CSF Granulocyte–macrophage colony-stimulating factor; IFN2 Interferon α-2, γ IFNg interferon-g; IL Interleukin, MCP-1 Monocyte chemoattractant protein-1, MIP-1b Macrophage inflammatory protein-1β, TNF- α Tumour necrosis factor-α, CAP Community-acquired pneumonia
