Fig. 3From: Endothelial Permeability and the Angiopoietin/Tie2 System Following Mild and Severe COVID-19Changes in endothelial resistance over time Human pulmonary (A) and renal (B) endothelial cells were exposed to plasma from COVID-19 patients collected at admission, week 1 and week 2 at the ward or intensive care and endothelial resistance was measured. Data represent median with interquartile range and were tested with Friedman test with Bonferroni post-hoc analysis and Wilcoxon signed rank test. * = p < 0.05, ** = p < 0.01, *** = p < 0.001Back to article page
