Well it
is a first of its kind, of sorts, so I think it falls into the "Hmmm, that's interesting" category, but nothing earth-shaking. I'm wondering if it isn't a result of questionnaire pushed on the Facebook JMT group:
Annual JMT Hiker Survey That JMT survey is very different, and conducted diligently by John Ladd. It does not pretend to be medical research, although it does cover injuries and illness, it mostly a catalogue of experiences and demographics. Very useful for fact-chaecking trail lore and mythology, too.
