Problems in the "Evidence"
of "Evidence-Based Medicine"
 

  ◊ The results show comparative efficacy of treatment for an "average"
      randomized patient, not for pertinent subgroups formed by such cogent
      clinical features as severity of symptoms, illness, co-morbidity, and other
      clinical nuances.

   ◊ The data do not include many types of treatments or patients seen
       in clinical practice.

   ◊ The authoritative aura may lead to major abuses that produce
       inappropriate guidelines or doctrinaire dogmas for clinical practice.
