Hi Hötzi,

» In other words, if patients are treated with the originator’s product, there is a 5% risk that it does not perform better (more efficient and/or safer) than placebo.

There is no more than a 5% risk of approving the test product (=concluding superiority) if the test product is not superior.

» If we would test for BE at the 2.5% level (95% CI) we would be overly strict and at the same time gain absolutely nothing in terms of the patient’s risk.

The patient's risk would be halved (max 2.5% chance of approving a non-BE product; CIs would get wider).

typeof(b[,1]) ##aha, integer?
b[,1]+1 ##then let me add 1

Best regards,

On two occasions I have been asked,—“Pray, Mr. Babbage,
if you put into the machine wrong figures,…
will the right answers come out?”

I am not able rightly to apprehend the kind of confusion of ideas
that could provoke such a question.    Charles Babbage
