Key Points

Equivalence testing for statistical methods indicates a viable approach for three-arm trials with multinomial outcomes.
A defined significance threshold of 0.05 is used to evaluate whether the results meet equivalence criteria.
The approach can facilitate better comparisons among various interventions tested in clinical scenarios.
These findings highlight the need for refined methods in trial design to enhance robustness and interpretation.
