Dear Helmut Schütz,
Thank you very much for your suggestions.
Your paper is very interesting and so professional.
And we will try to calculate the sample size with all pairwise treatment comparisons.
Notablly, you said that all versions of PASS require the standard deviation of the treatment difference as input. However, the paper of the Pilot Study Sample Size Rules of Thumb in PASS Sample Size Software Documentation did not present the standard deviation or any other parameter (see figure2 and figure3)


Did we ignore any important information?

Many thanks

BEST regards
