Dave,
    Do not take one article about anything involving medicine or physiology 
as a good source for information.  If this study were repeatable and found 
its way into accepted thinking within the practicing community, then maybe 
it would be worth considering.
    The study also deals with breath hold diving and DCS not SCUBA 
diving.  This may or may not make a difference with being exposed to a 
larger amount of nitrogen with SCUBA.
    One can manipulate medical studies and statistics to say whatever one 
desires.  Most people would be horrified if they knew what was studied and 
reported inside medical journals.
    Thanks for bringing this up, when I get a chance I will pull the 
references and take a look at it.
