From: A comparison of four different models of acute respiratory distress syndrome in sheep
Interleukin-6 (IL-6) concentration in plasma at the time point at which the criteria for ARDs was met = 0 h (a) and at the end of the experiment at T = 4 h (b). There was no difference in IL-6 concentration between all groups at the beginning (6 A). At the end of the experiment, the IL-6 concentration was significantly higher in the LPS iv group as compared to the other three groups (6 B; * p < 0.001). The concentration of IL-6 in plasma was higher in each corresponding group at the end of the experiment (T = 4 h), as compared to the time point at which the criteria for ARDs was met (T = 0 h), but this difference was only significant in the LPS iv group (a and b; * p < 0.001)
