Receiver operating characteristic (ROC) analysis of plasma DAMPs in COVID-19 patients and healthy donors (HDs). The sensitivity and specificity for both COVID-19 patients and HDs were calculated. The ROC curves of S100A8/A9 (A), HMGB1(B), SP-A (C), CIRBP(D) were plotted and the area under the curve (AUC) was calculated with the 95% confidence intervals (CIs) based on DeLong's method.
