Purpose of the study? [Power / Sample Size]
❝ […] if a study design is 5x5 cross over trial, reference, 3 treatments, and placebo, and I would like to estimate the sample size ?
See the subject line. If you will tell us the purpose of the study, we may help.
What do you want to demonstrate? Equivalence of the treatments to the reference and superiority of all to placebo or what?
