Discordant outliers [Outliers]
❝ maybe I'm only one who is confused with that statement, but:
❝ 3. The subject in question should be identified as an outlier for all parameters, for either the test or reference product, upon which the bioequivalence decision is to be based.
❝
❝ Either? Sorry for my poor grammar knowledge but 'either' is a kind of choice, right?
In the combination either – or, absolutely. If you drop the or it is a synonym for each (element of a set).
Either A or B: A ∨ B
Either of A, B, C: A ∧ B ∧ C
I guess HC means that it doesn’t matter whether an aberrant response is seen after test or reference. Agrees with ICH E9 Section 5.3:
Any outlier procedure set out in the protocol or the statistical analysis plan should be such as not to favour any treatment group a priori.
❝ So does it mean we need to find out the outliers using the datasets splitted by formulation, not for the ratio T/R?
Good point. If we split the dataset, we can’t run the model, right? Studentized residuals? Nada.
I guess HC talks about discordant outliers. In other words, it doesn’t matter whether the aberrant response is observed for the test or reference. Like it.

The quality of responses received is directly proportional to the quality of the question asked. 🚮
