Hi Mittyri,

❝ I would like to discuss some issues in FDC studies design.

❝ So... We have only 80% of probability to prove BEQ for ABC (20% of II type error) and 80% for XYZ.

❝ Final probability is 80%*80%=64%! :confused:

❝ Should we use another power for calculations (89%*89%=80%)?

You are thinking into the right direction. See also this thread. The question is: Are the two tests independent?
