How are they going to do the "sham" procedure? I am concerned that a sham operation either will not be blinded, or will not be ethicial. I understand Stanford was concidering a "sham" operation as well. I am very curious.
This is a bit off topic although we have discussed it here. You can answer me either with pm, here, or on another thread called "how can we design a trial to test the efficacy of this procedure?" or something like that. Thanks.
