How do you know if a trial is underpowered?
- If the confidence interval (CI) of the effect size INCLUDES the minimally important difference, your study is underpowered.
- If the confidence interval of the effect size EXCLUDES the minimally important difference, your study is negative.
What does it mean when you feel neutral?
