RE: ESTIMATION OF GLOMERULAR FILTRATION RATE WITH CREATININE- BASED VERSUS CYSTATIN C-BASED EQUATIONS IN KIDNEY TRANSPLANT RECIPIENTS (LETTER)

摘要

The interesting paper by Savaj and colleagues in a recent issue of the Iranian Journal of Kidney Diseases prompted me to make two comments that might be of interest to your readers. First, the variety of equations for the glomerular filtration rate (GFR) based on cystatin C is apparent rather than statistically significant. Second, it is almost inevitable that the modification of diet in renal disease (MDRD) equation is a better measure than the simpler expressions.
