This study conducted a secondary Bayesian reanalysis of a randomized controlled trial comparing high-flow nasal cannula (HFNC) and non-invasive ventilation (NIV) in infants with acute bronchiolitis. The analysis revealed that a non-inferiority margin of 0.15 in absolute risk reduction could imply a doubling of intubation odds, with a Number Needed to Harm of approximately 6.7.

Key findings

  • The Bayesian reanalysis indicated that a 0.15 non-inferiority ARR margin might imply a doubling of the odds of intubation.
  • The Number Needed to Harm (NNH) for HFNC compared to NIV was approximately 6.7.
  • The original analysis concluded non-inferiority using a fixed absolute margin.

Why it matters

Understanding the implications of non-inferiority margins is crucial for clinicians when interpreting trial results, as these margins can significantly affect treatment decisions and patient outcomes.
