This small study shows promise for this treatment protocol, but as the researchers are quick to point out, the results need to be verified in a much larger placebo-controlled trial. At this early stage, we do not know whether the improvements observed were a result of the placebo effect, as the study was not blinded. In addition, it could be 1 or a few aspects of the treatment protocol that made the difference, rather than all 4 steps. For example, the stomach acid suppressant may have been the key factor.
