Fischer exact two-tailed P-value for the comparison of proportions.
Median (range).
Unpaired t-test was used for the comparison between the survivors and non-survivors. n.s., not significant.
Score on admission.
PaO2 ≤ 75 mmHg without evidence of primary lung disease.
Ratio of partial pressure of arterial oxygen to forced inspiratory oxygen fraction of inspired oxygen <300.
Creatinine concentration of >3·5 mg/dl or hemodialysis or oliguria of <250 ml/24 h.
Disseminated intravascular coagulation (disseminated intravascular coagulation) represents prothrombin time or partial thromboplastin time of ≥1·2 times the upper normal limit plus d-dimers ≥500 or platelets ≤100 000/µl.
