; have there been double blind studies on this?
would it be fare to say even this type of study would not convince you NSD works unless you were doing these double blind studies using identical twins both HLA-B27+ with AS that lived their whole lives living in an identical environment, getting ill on the exact same day every time and eating the identical food (& quantity) for every meal since birth.
Sadly, it's not that easy. BECAUSE a fair, double blind study is either impossible or simply too difficult to conduct as it pertains to AS, it justifies my skepticism. AS is different, apparently, in nearly every single person it afflicts. The efficacy of remedies/cures/etc. varies from person to person. Therefore, without such a study, as difficult as it may be to conduct, I think that stating that a NSD will "definitely" work on every AS sufferer goes a bit too far. At least in my opinion.
