Table 2 Comparison of subjects with chronic kidney disease (CKD) estimated by the Cockcroft-Gault, abbreviated MDRD and CKD-EPI equations
Cockcroft-Gault | Abbreviated MDRD | CKD-EPI | P-value | |
|---|---|---|---|---|
Frequency CKD stage 3 or higher, N (%) | 80 (23.7%) | 74 (21.1%) | 76 (21.7%) | <0.001 |
Stage 3 (30–59 mL/min/1.73 m2) | 78 (97.5%) | 73 (98.7%) | 75 (98.7%) | 0.9 |
Stage 4 (15–29 mL/min/1.73 m2) | 2 (2.5%) | 1 (1.4%) | 1 (1.3%) | 0.8 |
Stage 5 (<15 mL/min/1.73 m2) | 0 | 0 | 0 | 0.9 |
Serum creatinine, μmol/L, median (IQR) | 97 (80, 115) | 106 (88, 124) | 106 (88, 124) | <0.001c |
Estimated glomerular filtration rate, median (IQR) | 47.5 (41, 55) | 53 (45, 55) | 52 (47, 57) | <0.001c |
