Dear Helmut and all,

If one test and two references of different regions are tested in a bioequivalence study, is it necessary a α adjustment?

In my case, we want to demonstrate if the test product is bioequivalent to R1 (European product reference) or if test product is bioequivalent to R2 (Reference product in the United Kingdom).

If I have not misunderstood, in this case, alpha should be penalized, even if they are from different regions and to market in different regions because of the word "OR"?

Is there a way to not penalize alpha? If the "O" is changed to "AND"? Executing two different clinical trials (one for Europe and one for the UK)?

Best regards,

The rise of biometry in this 20th century,
like that of geometry in the 3rd century before Christ,
seems to mark out one of the great ages or critical periods
in the advance of the human understanding.    R.A. Fisher
