IL6 and acute respiratory distress syndrome: When stratified by presence or absence of ARDS within 5 days of ICU admission, the concentration of IL‐6 and sICAM‐1 concentrations were significantly increased in Sepsis+ARDS patient plasma compared with healthy plasma patient following incubation in the EC lumens (median 1584.2 pg/mL, IQR 1892.0 vs. 621.8 pg/mL, IQR 258.1, p = 0.03 and 100118.5 pg/mL, IQR 159832.3 vs. −19934.6 pg/mL, IQR 61657.0, p = 0.04 for IL‐6 and sICAM‐1, respectively; Figure 4).
