Dear all,
as you may know, in many clinical trials it is often not ethically acceptable to include a control group with no treatment. One option is to use a wait-list, but in many cases we end up comparing two interventions. It is in such scenario that I have been recommended to prepare a noninferiority trial, instead of the more typical superiority trial.
Does any of you have in mind any resource or material to prepare this type of study? I am especially interested in sample size estimation and statistical analyses to be proposed in the protocol.
Thank you,
