Table 3 summarizes the significant associations between the cytokine levels and COVID-19 severity where GM-CSF, IL-1α, IL-1Ra, IL-8, IP-10, and MCP-1 showed significant positive correlation patterns while IL-12p70, IL-13, IL-2, and IFN-γ showed significant negative correlation patterns with COVID-19 severity. This evidence concerns the gene IL2 and COVID-19.
