^aBAL, Bronchoalveolar lavage fluid; CPIS, Clinical Pulmonary Infection Score; CRP, C-reactive protein; PCT, Procalcitonin; PTX3, Pentraxin 3; SE, standard error; sTREM-1, Soluble triggering receptor expressed on myeloid cells 1. ^bCould not be determined because all values were >0.5 mg/dl. ^cCould not be determined, as estimates were not reliable because of convergence problems of the statistical model.
