Univariate analysis for prediction of microbiologically confirmed pneumonia a
| Variables | Univariate β | SE | P -value |
|---|---|---|---|
| BAL fluid PTX3 ≥1 ng/ml | 2.784 | 0.792 | <0.001 |
| Plasma PTX3 ≥130 ng/ml | 0.742 | 0.576 | 0.198 |
| Plasma PCT ≥0.5 ng/ml | 0.506 | 0.532 | 0.342 |
| Plasma CRP ≥0.5 mg/dlb | – | – | – |
| BAL fluid sTREM-1 ≥5 pg/ml | 0.438 | 0.507 | 0.389 |
| Plasma sTREM-1 ≥5 pg/mlc | – | – | – |
| CPIS ≥7 | −0.192 | 1.183 | 0.871 |
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.
