Key Points
- Non-inferiority (NI) trials are indicated when there are other effective treatment options or where it would unethical to expose a group to placebo
- Acinetobacter baumannii-calcoaceticus (ABC) is seen in hospital acquired infections and presents a clinical challenge to practitioners given its increasing resistance patterns
- NI margins are important components to critique when reviewing these trials to determine clinical implications and whether the margin is clinically justifiable
- How inferior is considered "non-inferior"? --> Tune in to find out!
