Dear all,

Excuse the somewhat off-topic question. I need to do sample size calculations for a clinical trial with 4-5 arms. I've seen lots of calculations and examples for comparing two groups. Are there any special considerations that I should take into account when there are more than 2 groups? Adjusting p-values, etc.?

Thanks in advance for any suggestions.
