Seth: I don't know what your interpretation/recollection is/was of Mr. Devor's layman statistics, but I can assure you that all of the numbers I used were directly from Mr. Devor's posting on this list. I did not rewrite Mr. Devor's investigative history. As to the report in "The Lancet" on 105 patients; Those numbers indicate a 5.7% failure rate Which is only approx 2.1 % better than that shown by Mr. Devors numbers. Still not good enough -->for me<--. Regression in 9.2 months is fairly fast. It can happen anywhere from 4 months to over 2 years. I cannot help but wonder how many more will be added to the list of 6 over the next two years. Que sera sera! VernD
