IL6 and acute respiratory distress syndrome: The individual concentrations of these cytokines in the controls and ALI patients were as follows: for IL-1β, 14.3 pg/mL (range 1.94-98.35) versus 421.44 pg/mL (range 12.67-1865.33, P < 0.001; Figure 1A); for IL-6, 23.14 pg/mL (range 2.14-112.33) versus 342.76 pg/mL (range 31.34-1783.47, P < 0.001; Figure 1B); for IL-15, 33.62 pg/mL (range 5.32-165.88) versus 309.36 pg/mL (range 45.33-1157.85, P < 0.001; Figure 1C); and for TNF-α, 45.39 pg/mL (range 1.68-136.57) versus 396.43 pg/mL (range 23.74-2315.63, P < 0.001; Figure 1D).
