Association of microcirculation and endothelial glycocalyx parameters. a–c Boxplots of PVD, PPV, and MFI values after dichotomizing the sepsis group by the median PBR values. d–f Boxplots of septic patients classified on the basis of their microcirculation parameters into the following groups: “intact” (PPV > 90% and MFI > 2.9), “at risk” (PPV ≤ 90% or MFI ≤ 2.9), and “impaired” (PPV ≤ 90% and MFI ≤ 2.9). No difference was observed between the groups regarding PBR, syn-1 levels, or MAP. ICU, intensive care unit; MAP, mean arterial pressure; MFI, microvascular flow index; PBR, perfused boundary region; PPV, proportion of perfused vessels; PVD, perfused vessel density; syn-1, syndecan-1
