Ugggh, this is sort of one of those questions. The one I want to ask. I have heard a
lot about EMR and its proposed harm. Can someone give me pointers to go literature
on the subject, from a thoughtful and nuetral perspective. As far as I have seen all
I can get is: "It's bad" (Health Activists) and "Nothing Wrong"(EPRI --- Electrical
Power Rsearch Institues).
Since I am we all use this sort of equipment it would be nice if there was any
reasearch on it, and how it was done. Beyond the sort of SPSS/SAS correlate
everything with everything and guess. Actually it should be correlate everything
with everything and then pick a few things for extensive research.
Have Fun
Sends Steve
