Table 3. Multivariate logistic regression models for MEP associations with critical outcomes: with and without MIP

From: The relationship between maximal expiratory pressure values and critical outcomes in mechanically ventilated patients: a post hoc analysis of an observational study

  Extubation failure Death at 30 days
OR 95% CI p value OR 95% CI p value
Model without MIP
 MEP 0.97 (0.94–0.99) 0.013 0.99 (0.98–1) 0.53
 Principal component 1 score 0.59 (0.40–0.89) 0.011 1.04 (0.75–1.4) 0.81
Model with MIP
 MEP 0.99 (0.96–1.02) 0.50 1 (0.98–1.02 0.46
 MIP 0.92 (0.86–0.99) 0.019 0.97 (0.93–1) 0.08
 Principal component 1 score 0.61 (0.40–0.92) 0.019 1.03 (0.74–1.42) 0.86
