Glomerular filtration rate and serum phosphate: an inverse relationship diluted by age

Abstract

GFR differences in the range >or=60 mL/min x 1.73 m(2) are inversely and independently related to serum phosphate. The relationship is undetectable without age-controlled procedures because, for serum phosphate, the effect of GFR differences above >or=60 mL/min x 1.73 m(2) is much smaller than the effect of age.
