Hi ElMaestro,

❝ a 90% CI that doesn't spanover 1.0 should generally be no problem. It means that Test and Ref differ but so be it; all products differ and sometimes we can even detect it as a significant treatment effect as in your case. The primary equivalence criterion is still just a 90% CI within the acceptance range. Statistically different isn't necessarily clinically relevant.

This is my take on it as well and how I plan on pushing it (gently). What do you mean by "quality-focused"?

Thank you for your feedback.
