Hello, both,

» » At this situation, should this subject's data with one period be included in the BE assessment?

» No, you could not.

We do not need a T-R comparison in each subject to do an analysis. We are just stuck in that paradigm. We could in principle fit a model with missing period data. And all data could be used for the calculation of the CI.
I do not know why there is a regulatory tradition for only using completers - I would say there is even a potential scientific and ethical advantage of using all period data.

I could be wrong, but...

Best regards,

No, of course you do not need to audit your CRO if it was inspected in 1968 by the agency of Crabongostan.
