Box-plot and individual data points showing microcirculatory alterations in IRCU/ICU patients according to the severity of ARDS. The distribution of StO2 and ReO2 was significantly different among patients according to the severity of ARDS. A post hoc Tukey comparison showed that severe ARDS patients had higher StO2 values as compared to moderate ARDS, and lower ReO2 values, as compared to mild ARDS. The distribution of DeO2 among groups did not reach statistical significance (p = 0.053)
