To conclude, our data are of importance, as this is the first study to our knowledge that analyzes and compares CRP with the other 12 key predictors of disease severity and mortality, previously reported for COVID-19 (including suPAR, sTREM-1, HGF, MCP-1, LDH), while including mild, moderate and severe cases. The gene discussed is CCL2; the disease is COVID-19.
