How do you decide difference between means vs superiority margin, if both are clinically relevant only?

Good explanation but madam you are recalculating the already calculated sample size rather calculating a new sample size using the findings of the previous studies. It would be much better if for each example you extract the data from the findings of the previous studies for new sample size calculation as many of the terms are not clear. like what is expected SD or combined SD. this is just justification and verification of already calculated sample sizes.
