Evidence-based medicine is the conscientious,
explicit and judicious use of current best evidence
in making decisions about the care of individual
patients. The practice of evidence-based medicine
means integrating individual clinical expertise
with the best available external clinical evidence
from systematic research. - David L. Sackett
(BMJ 1996; 312: 71-2)
