The Modification of Diet in Renal Disease (MDRD) equation is widely used for the estimation of glomerular filtration rate (GFR) from plasma creatinine. It has been well validated in patients with various degrees of impaired kidney function, but not in patients with end-stage renal disease (ESRD). Plasma creatinine is determined by GFR and muscle mass. Importance of the latter may increase at low GFR. Our aim was to firstly compare estimated GFR (eGFR by MDRD equation) with measured GFR (mGFR, mean of creatinine and urea clearance) just before the start of dialysis. Secondly, the relationship of eGFR and mGFR with mortality and muscle mass was analysed.
