Fig. 4. Protein C and soluble triggering receptor expressed on myeloid cells (sTREM-1) concentrations in blind bronchoalveolar lavage. (  A ) Protein C concentration in survived and nonsurvived patients. (  B ) sTREM-1 concentration in survived and nonsurvived patients. There was no significant difference between survived and nonsurvived patients for both blind bronchoalveolar lavage protein C and sTREM-1.  Open and closed circles signify numbers out of range (mean [25, 75]) in each group of patients.
