Hi ElMaestro,

Good point – I missed that! In the past I did not adjust because only one will be marketed (i.e., the entire patient’s risk lies with this product). However, some regulatory statisticians (you know, coffee break chats) seem to be more strict because one gets two chances of passing. Too lazy to crawl the supplementary material of your paper about pilot studies: Is such a case covered?

I believe there is no philosophical high-road in science,
with epistemological signposts. No, we are in a jungle
and find our way by trial and error,
building our road behind us as we proceed.    Max Born
