We are planning to measure some cytokines in patients with MS comparing
between a group with treatment and control, but there have not been
literatures regarding these measurements, so we do not have an estimated
mean and standard deviation. Is there a way to estimate a sample size?
(our IRB really wants to see sample size estimate.) Thanks.
