HO-1 mRNA levels are associated with COVID-19 progression and outcome. HO-1 mRNA upregulation in whole blood samples from (a) critical versus severe patients (b) survivors versus non-survivors. Receiver operating characteristic (ROC) curves of HO-1 mRNA levels for prediction of need for intensive care (c) and mortality (d). The corresponding areas under the curve (AUC), p, sensitivity and specificity, odd ratio and cut off values are represented in (e). Statistical analysis was performed by Mann–Whitney U test. * p < 0.05.
