- Oxygen flow at ICU admission was dichotomized below or over 9 l/min
- Patients form IVNICTUS study were compared to patients from HIGH study
- ARF aetiology was dichotomized between ARF related to bacterial or viral pneumonia versus all other reason of ARF
- SOFA Day 1 was sequential organ failure assessment
- ROX index was used as continuous variable
- Characteristics of the multivariate model
- Hosmer and Lemeshow goodness of fit test p = 0.65
- The AUC of the ROC curve of the predictive model = 0.66
- The relationship between ROX index and lod(odds) of intubation was linear
- ARF acute respiratory failure, NIV non-invasive ventilation, OR odds ratio, CI confidence interval
