Hi Ken,

I once ran 2 2-way crossover studies with a 90 day washout (management didn't want to take a chance with a parallel study design). The studies were okay, we had 5-10 dropouts.

The sample size for parallel design (I think Helmut mentioned this to me before, right Helmut? ) is based on the total CV (intersubject CV and intrasubject CV).

90% CI computation will be done using the intersubject CV¹
