The rationale for always adjusting GFR to body surface area apparently dates
back to the 19th century when the 'law of surface area' was used in
physiology and medicine to calculate fluid and drug requirements.(1) In the
middle of the 20th century, the application of BSA formulae to urea
clearance seemed to give children and adults comparable numerical values,(2)
and since then the utilisation of this adjustment has fallen, largely
unquestioned, into common use.

In fact, according to the Ciba Geigy books this formula, which is in common
use, is based on only 9 (yes, nine) subjects. So much for evidence based
medicine.
