Finally, there was a significant increase in CRP, ferritin and D-dimer in severe and moderate COVID-19 patients compared with controls (P2 < 0.001, P3 < 0.001) and a significant increase in CRP (P1 = 0.044) and ferritin (P1 = 0.03) in severe COVID-19 patients compared to moderate COVID-19 patients (Table 1). The gene discussed is CRP; the disease is COVID-19.
