Changes of PCT and IL-1β concentrations in patients with sepsis-induced ARDS during treatment after ICU admission. Data in the control group (shown in black empty squares) were compared to data in the DEX group (shown in red solid squares) over a period of 6 days. Pound sign (#) indicates p < 0.05 when the parameter in the DEX group is compared to that in the control group at the same time. Asterisk (*) indicates p < 0.05 when the parameter is compared to that on day 0 within the same group. The dotted line in each graph indicates a mild or non-severe value of cytokine, which equals to a) 2 ng/mL PCT and b) 12 pg/mL IL-1β
