Registerdifferent results from diff. software? [Power / Sample Size]
Good evening and Happy New Year,
I would like to receive an answer to my question.
After a pilot bioequivalence study, I obtained an intraCV for Cmax of 34%.
Sample size for the pivotal study obtained after statistical calculation was of 36 subjects.
The sponsor representative showed me other calculus for this parameter using different software, obtaining a number of 48 subjects.
Who is right in this case?
Thank you very much, Jo
