CRP and COVID-19: Univariate logistic regression analysis showed that age (≥60 years V < 60 years) (P < 0.001), dyspnea (yes V no) (P < 0.001), lymphocyte count (low V normal) (P = 0.001), CRP (high V normal) (P < 0.001) and IL-6 (high V normal) (P < 0.001) were correlated with the occurrence of severe type out of the common type of COVID-19 (Table 2).
