Dear All!
Thanks for the discussion!

❝ Now you confused me (even reading Ravuri’s OP again did not help). If periods are analyzed in single, separate batches it should not matter in a crossover due to the randomization. Prerequisite: Always keep the order of the batches for all subjects p1 → p2 → …

❝

❝ What would not work:

A paired design.
❝
Periods split into different batches.

I believe that ultimately separate batches in a run is not an issue. Over here the calibration curve equation used will be the same. But when we are running P1 and P2 in different run (not batches), then definitely it could have direct impact on BE Out come.

Regards,
D Shah
