Hi All,

As my statistics background is rather poor (shame on me) I can't understand purpose of pooled CV in BE-studies.

Unless I am mistaken this parameters should be calculated when there are several studies with different CVs and we need "adequate" CV (correct? :confused:).

But what prevents us from using the highest CV for sample size calculation?
Any ambushes there? :-)
