Hello Mittyri,

❝ 1. Is it obligatory EMA's requirement to use Group effect in the model in all cases when there is more than one group? Any experience of LoDs due to absence of Group effect in the statistical model?

Just include the term.... that can't be bad in a regulatory sense and it can't be a burden to you, right?

❝ 2. What kind of statistical model is preffered for Europe ..

❝ Something like that:

❝ Fixed: sequence, period, treatment, group, subject(sequence)

Sounds right to me, and I've had thumbs up in sc.advices.

❝ 3. Did you ever got the requests from EMA experts about calculating the CI into one of the groups as for FDA submision?

Not sure what you are actually asking. I have never heard a EU regulator ask for something the FDA want just because of FDA's request in itself.

Hötzi: Enjoy your holidays. I am confident there will be good news in your mehlbox when you return
