Ann: 36-Month Results of Phase 3 Trial in Chronic Low Back Pain, page-189

As you should well know, the purpose of having a control that has the same process as the treated group is to keep the trial blinded. As others have pointed out yesterday , there is plenty of science and past data about NA and it's effects.

Now instead of getting your lessons from well informed hear on HC perhaps it's time to also contribute. The charts that I posted display data about ( LS )
As a potential Dr you will need to understand LS and the likely benefit to a patient. I note that if a patient was to get our cell therapy they have a reasonable chance of reduced pain by 36 points. What would this mean for the patient? Would you consider that there is a problem enrolling patients knowing that half of them wont get the treatment.
