Hi Dennis,

❝ ❝ You hope that the complication rates in group A (with medicine) are lower than in group B (without medicine), right?


❝ However, we try to show the complication rates in group B (without medicine) are lower (or not worse or non-inferiority) than in group A (with medicine), …


Essentially you are trying to show that the medicine doesn’t perform better than placebo (assuming the study is double-blind). :-D:blind:

❝ … duo to the medicine is very expensive.


Likely you will face problems with the IEC/IRB:It is the job of the IEC/IRB to make a benefit/risk-assessment for the subjects in the study. To assess a potential socio-econommic advantage for the health system is not in the job description of the members.

❝ Is there any other probelm for the design?


IMHO, ethics.
