Could you please explain the following points?
- Is there any thumb rule (apart from %CV more than 30), when to use three way against four way cross over design?
- As we know, four way design reduces the sample size compared to three way designs, is there any additional advantage which four way design give (in terms of overall outcome of the study)?
- Even though variability is less than 30%, we perform three or four ways cross over study, would it enhances chance of passing the study (i.e forced BE) compared to simple two way design?
Many Thanks in advance
