In the absence of these definitive respiratory values during treatment for non–ECMO-referred patients, but with a view to exploring the hypothesis that Haeck et al outline, we conducted 2 sensitivity analyses limiting comparison of the ECMO-referred patients to non–ECMO-referred patients treated in critical care units either with a higher volume of ventilated patients or with a lower standardized mortality ratio—characteristics associated with better outcomes for ventilated patients and for all patients, respectively. Our base-case results were robust to these sensitivity analyses.
