As determined by the multivariate analysis, CRP (OR 1.026, 95% CI 1.004–1.048, P = 0.018) and lymphocyte proportion (OR 0.924, 95% CI 0.871–0.980, P = 0.009) were significantly associated with the risk of developing severe events in fevered adult COVID-19 patients (Table 5). Here, CRP is linked to COVID-19.
