- Correlation of the endotracheal tube cuff volume predicted by the regression model with the actual volume in the validation group (n=37).
| Parameter | Predicted volume for testing | |
|---|---|---|
| r | P-value* | |
| ETT cuff volume | 0.586 | <0.001 |
↵* Pearson correlation test (R2=0.343). ETT: endotracheal tube, r: correlation coefficient
