Newfoundland: No Benefit to Liberation

It sure would be good to know how the study was conducted: http://updatednews.ca/2012/06/07/no-benefit-to-controversial-ms-treatment-says-n-l-study/.  Could it be because the symptoms that are improved (fatigue, balance, autonomic functions) are hard to measure... and so there is no "measurable" impact?  What makes this suspicious about the whole story is that many of the news stories again mention a) the silly/suspect FDA announcement of last month and b) the two Canadians who have died from complications after the procedure (without mentioning the details or the fact that THOUSANDS of Canadians have been liberated).  Sounds like lazy news editors all reading from the same script... wonder who wrote the script?
