CRP and COVID-19: Evaluation of the prognostic potential of COVID-19 severity biomarkers CRP, PCT and the SOFA score showed, that these readily available standard of care markers were not able to reliably predict patient outcome at day 0, with AUROC curve values comparable to random classification (CRP AUROC = 0.507 95% CI = 0.261–0.753, PCT AUROC = 0.654 95% CI = 0.416–0.892, SOFA AUROC = 0.698 95% CI = 0.492–0.904).
