Comparison and association of endothelial dysfunction and glycocalyx shedding related markers in coronavirus disease 2019 (COVID-19) patients and healthy controls. Levels of a) angiopoietin 2 (ANG2), b) soluble thrombomodulin (sTM) and c) soluble syndecan-1 (sSDC1) between healthy controls (n=12), COVID-19 non-intensive care unit (ICU) patients (n=8), COVID-19 ICU patients (n=26) and recovered patients (n=18). Pearson's correlation between d) ANG2 and sTM, e) ANG2 and sSDC1, f) sTM and sSDC1. Graphs represent mean±sd. One-way ANOVA followed by Tukey's multiple comparisons test and Pearson's correlation analysis were performed. *: p<0.05; **: p<0.01; ***: p<0.001.
