In a meta-analysis to determine the predictors of COVID-19 severity, Kurniawan et al. [21] found an average of 36.88 mg/L higher CRP, an average of 0.07 ng/mL higher procalcitonin, an average of 0.043 μg/L higher D-dimer, and an average lower -4.58 g/L albumin in severe patients when compare mild patients. The gene discussed is CRP; the disease is COVID-19.
