Dear D_Labes!

❝ ❝ […] See also this post.

❝ in the linked post you do not recommend a group by period interaction.

❝ How can we then interpret the paragraph VII A "Studies in multiple groups" in the FDA guidance

❝ "… In particular, the model should reflect the fact that the periods for the first group are different from the periods for the second group…".

❝ To my understanding this calls for group by period interaction.?


Please see also this post. But of course, this is just my personal opinion…
