    Differing definitions of weaning failure may influence statistical heterogeneity and prediction targets in diaphragm ultrasound studies.

  • 2

    Weaning and extubation are distinct processes, and diaphragm ultrasound timing affects its predictive value for weaning outcomes.

  • 3

    Combining SBT failure and extubation failure into one endpoint may conflate distinct clinical questions regarding patient readiness.

  • 4

    The highest pooled area under the curve for diaphragmatic excursion should be viewed as descriptive, not indicative of superiority.

  • 5

    Future analyses should focus on AECOPD cohorts where diaphragm ultrasound parameters are assessed in the same participants.
