Table 6 Relative mortality risks in categories of eGFR for 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

  Hazard ratio (95% CI)
  < 30 ml/min 30-44 ml/min 45-59 ml/min >60 ml/min
C-G 1.9 (1.1-3.3)* 1.3 (0.9-1.9) 1.0 (0.7-1.5) 1
MDRD 3.5 (1.8-6.7)** 1.6 (1.2-2.2)** 1.1 (0.9-1.3) 1
CKD-EPI 2.4 (0.9-6.4) 1.3 (0.9-1.8) 1.1 (0.9-1.5) 1
  1. All hazard ratios are adjusted for sex.
  2. C-G clearance is in ml/min, MDRD and CKD-EPI clearance is in ml/min/1.73 m2.
  3. Abbreviations: C-G Cockcroft-Gault, MDRD Modification of Diet in Renal Disease, CKD-EPI Chronic Kidney Disease Epidemiology Collaboration clearance.
  4. *P < 0.05, ** P ≤ 0.01 compared to the reference group (>60 ml/min).
