Hi All:

I am writing a study protocol aimed to compare a new screening technique
called "electromammography" with conventional methods of screening for
breast cancer.

Would highly appreciate if anyone can provide some wisdom whether there
exists a way to calculate the study power and sample size for situations
where two or more screening methods are being compared

TIA,
Arin
