So what would you make of the following comment: "Equipoise is an irrelevance. Patients are entered onto the trial because the trialists believe that the experimental treatment is better. The control group treatment should be as good as that available outside the trial. Experimentation continues until either the trialists are convinced they are wrong (equipoise is reached) or they convince Society they are right."
