If the forum can throw some light on the addressing following points on carry-over.
what I am trying to understand is how to answer - Unequal carryover (between Test and RLD) effect on potential inflation of Type-1 error and bias in the BE conclusions"

How to measure carry-over (any particular PK parameters or in vitro measures?)
How to assess equal or unequal carryover?
Differences in 1st order or other order carry-over
Is there a cut-off to call negligible carry-over
What are the statistical tests to call it a unequal carry-over or no un-equal carry-over.
How to factor or apply any corrections of observed carry-over in BE and RSABE calculations?

I realize these are loaded questions but any true insight that gets buying by EMA or FDA is much appreciated.
