FIGURE 2.

Associations of neutrophil elastase (NE) with components of neutrophil extracellular traps (NETs), clinical features, and biomarkers of severity and multi‐visceral harm of COVID. Significant associations of NE were reported with blood concentration of myeloperoxidase (MPO)‐DNA and histone‐DNA, blood counts of neutrophils, neutrophil/lymphocyte ratio, and blood biomarkers of multi‐visceral harm, including urea, SaO2, troponin‐T, lactate dehydrogenase (LDH), D‐dimer, and fibrinogen. Correlations were assessed by Spearman's rank correlation
