Image caption:
NETs and NETosis markers by clinical group. a Myeloperoxidase (MPO)-DNA, b peroxidase activity, and c cell-free DNA (cf-DNA) are compared in ventilator associated pneumonia (VAP) with and without acute respiratory distress syndrome (ARDS). MPO-DNA is higher in ARDS patients with VAP. P values are for Kruskal-Wallis (nonparametric analysis of variance (ANOVA) with post-test Dunn's to account for multiple pairwise tests). Error bars show the median and interquartile range. ***p<0.0001, *p<0.05
