Dear Helmut and everybody! Sorry if I posted my question on the wrong place (first time posting on this forum). I used the formula presented on slides 25-26 (link below) on a clinical protocol as justification for sample size calculation and the mexican regulatory agency asked for a scientific justification or a bibliography where the robustness of the formula can be proved/demosntrated. Do you have the specific reference of this? Thanks in advance, regards

Monica
