post hoc power [Power / Sample Size]
Dear,
It has been seen that In protocol, larger sample size is selected to just pass the study without any scientific justification or selecting high T/R in sample size calculation. Therefore, in many cases, post hoc power is more than 100% or nearly 100%. It is like forced bio-equivalence.
Does regulator seek justification for this?
Thanks and Regards...
