Application: Superiority, Equivalence, Non-inferiority
As discussed in the Huson article that is one of this week's Required Resources, confidence intervals can demonstrate superiority, equivalence, or non-inferiority. Each circumstance has a different meaning.
To prepare for this Application Assignment, review the Curley article, "Effect of Prone Positioning on Clinical Outcomes in Children with Acute Lung Injury: A Randomized Controlled Trial."
To complete this Application Assignment, that answers the following questions:
- Describe the hypothesis that was tested in this trial.
- What statistical method was used to test the hypothesis?
- Why was it used?
- Was the hypothesis proven or rejected?
- What was the confidence interval for the treatment group and what was the confidence interval for the control group?
- Did the results demonstrate superiority, equivalence, or non-inferiority? Explain why.
