RegisterCV from CI [Power / Sample Size]
Hi Helmut,
Thank you for the explanation
Probably, most of the times we would actually know the PE from a previous study together with the CI. That's why I would not see the need the recalculate the PE (as the GMR for either AUCs or Cmaxs). But I completely agree that if we get from a published article only the information about the GMR limits for AUC or Cmax, then this is a very clever way of deriving the CVintra.
Couple of more questions:

Couple of more questions:
- Presumably, n1 and n2 are form the previous study, right?
- Where 0.91 and 1.15 are coming from? Did you select them just as an example or there is a particular reason?
