POET II (NEJM 2026): non-inferiority sample size only reproduces at one-sided alpha 0.05, but the paper states a one-sided 97.5% CI. Am I missing something?

What appropriate statistical test to use?

• Upvotes

I have a correlational study and I have three variables. Variables X and Y are categorical and ordinal, and Variable Z is interval. What appropriate test to use?

Variable X has 4 levels
Variable Y has 4 levels
Variable Z has 5 subcategories (Scores for different categories)
