Table 4 Multivariate analysis of factors associated with the need for invasive mechanical ventilation during ICU stay

From: Severe varicella-zoster virus pneumonia: a multicenter cohort study

Variable OR (CI 95%) p
SOFA score at day 1 (per point increment) 1.90 (1.33–2.70) <0.001
Oxygen flow at ICU admission, L/min (per L/min increment) 1.25 (1.08–1.45) 0.004
Early bacterial co-infection 14.94 (2.00–111.8) 0.009
  1. Results are presented for the imputed data
  2. Candidate predictors were: age, any comorbidity, underlying immunosuppression, SOFA score at day 1, oxygen flow at ICU admission, alveolar consolidation on chest X-ray, antibiotics at ICU admission, and early bacterial co-infection
  3. CI confidence interval, ICU intensive care unit, OR odds ratio, SOFA Sequential Organ Failure Assessment
