Fig. 2From: Circulating endothelial extracellular vesicle signatures correspond with ICU requirement: an exploratory study in COVID-19 patientsA Representative results of nanoparticle tracking analysis B, C Cumulative and time-dependent concentration of particles. D, E Cumulative and time-dependent average diameter of particles. One-way analyses of variance or Kruskal–Wallis tests were performed to compare time points or data from pooled sampling points. *p < 0.05; **p < 0.01, ***p < 0.001, ns non-significantBack to article page
