Measured and estimated GFR by CKD-EPI equations, with and without race adjustment.
| mGFR51Cr-EDTA | eGFRCr (no race adjustment) | eGFRCr (with race adjustment) | eGFRCr-Cys (no race adjustment) | eGFRCr-Cys (with race adjustment) | |
|---|---|---|---|---|---|
| All participants (n = 100) | 46.7 ± 29.2 | 47.8 ± 30.1 | 52.7 ± 34.9∗ | 46.4 ± 30.3 | 48.8 ± 32.2 |
| White (n = 39) | 41.9 ± 23.4 | 43.7 ± 27.7 | — | 41.6 ± 27.4 | — |
| African Brazilian (n = 61) | 49.8 ± 32.2 | 50.4 ± 32.7 | 58.4 ± 37.9∗ | 49.4 ± 31.8 | 53.4 ± 34.4∗∗ |
Values are expressed as mL/min/1.73 m2. mGFR: measured glomerular filtration rate; eGFR: estimated glomerular filtration rate; Cr: creatinine; Cys: cystatin C. ∗P < 0.001 vs mGFR; ∗∗P < 0.05 vs mGFR.
