[image]Cause otherwise eventual period effects would not mean out. ;-)

Given, sometimes one has to assume lacking period effects and everybody is happy with that. If an originator explores whether the drug follows linear PK, we have a paired design (SD → saturation → steady state) and compare AUC0–τ with AUC0–∞. A crossover would be a logistic nightmare.

Exactly.

» […] For a parallel trial I think I want group in the model. If regulators don't like this, they can ask me to take it away. I happily do so without protesting. I am a sheep at that point. But not until then. :-D

Agree again.

completely disappeared from large sectors
