Table 1 Formulas of C-G, MDRD and CKD-EPI

From: Performance of Cockcroft-Gault, MDRD, and CKD-EPI in estimating prevalence of renal function and predicting survival in the oldest old

  Gender Serum creatinine* eGFR (ml/min/1.73 m2)
Cockroft-Gault Female All ((140- age) × bodyweight/serum creatinine) × 0.85
  Male All (140- age) × bodyweight/serum creatinine
MDRD Female All 175 × (serum creatinine/88.4)- 1.154 × age-0.203 × 0.742
  Male All 175 × (serum creatinine/88.4)- 1.154 × age-0.203
CKD-EPI Female ≤ 62 144 × (serum creatinine/88.4/0.7)-0.329 × (0.993)age
  Female > 62 144 × (serum creatinine/88.4/0.7)-1.209 x (0.993)age
  Male ≤ 80 141 × (serum creatinine/88.4/0.7)-0.411 × (0.993)age
  Male > 80 141 × (serum creatinine/88.4/0.7)- 1.209 × (0.993)age
  1. *Serum creatinine is stated in μmol/L.
  2. Abbreviations: eGFR estimated glomerular filtration rate, MDRD modification of diet in renal disease formula, CKD-EPI chronic kidney disease epidemiology equation.
  3. Because all our individuals were of the Caucasian race the multiplier factor for race was not applied.
