  1. OR odds ratio, CI confidence interval, Crs static compliance of the respiratory system
  2. aAdjusted odds ratios (ORs), and their confidence interval (CI) were determined using multivariate logistic regression with backward selection. Variables entered in the models were age, sex, chronic hypertension, Charlson comorbidity index, plateau pressure, compliance of the respiratory system, and PaO2/FiO2 ratio in model 1 replacing Crs by Crs/IBW in model 2. As Crs/IBW was not retained in the final model, OR are identical for the other variables
  3. n  = 365 and 359 patients for model 1 and 2, respectively
