Hi All,

Is it possible to make imbalanced Randomization sequence before entering the study?

For example, using 33 subjects for 2 treatment, 2 sequence, 4 period cross over study.

In my opinion, I don't accept this as despite the fact of the possibility of getting imbalanced sequence as a result of subject withdrawal, but I think that this does not mean that it is acceptable to perform imbalanced randomization from the beginning.

I want your opinion asap.
