From: Usefulness of open lung biopsy in mechanically ventilated patients with undiagnosed diffuse pulmonary infiltrates: influence of comorbidities and organ dysfunction

Variable P Odds ratio 95% CI
CCS 0.041 1.57 1.02–2.43
Number of organ dysfunctions 0.047 2.85 1.02–8.01
SOFAolb 0.013 1.55 1.10–2.19
SOFAmax 0.055 1.30 0.99–1.70
PaO2/FiO2 ratioon OLB day 0.023 0.985 0.973–0.998
Time to OLB, days 0.086 1.18 0.98–1.43
OLB complication 0.184 2.50 0.65–9.65
Immunocompromised status 0.146 0.31 0.67–1.50
  1. CCS, Charlson age–comorbidity score; SOFAolb, SOFA (Sequential Organ Failure Assessment) score at the day of open lung biopsy; SOFAmax, maximum SOFA score; OLB, open lung biopsy; time to OLB, days from mechanical ventilation to OLB; CI, confidence interval.
