Table 2. Mean serum creatinine and categories of estimated glomerular filtration rate (eGFR) in the general population cohort.
| Variables | Mean (95% CI) |
|---|---|
| Measurements | |
| Serum creatinine (mg/dl) | 0.75 (0.74–0.75) |
| eGFR (ml/min/1.73m 2) | |
| CKD-EPI equation * 1 | 109.3 (108.8–109.9) |
| MDRD equation * | 106.2 (105.4–107.1) |
| Individuals n(%) | |
| Category of level of eGFR | |
| Normal eGFR (≥90 ml/min per 1.73 m 2) | 4,792 (80.15) |
| Low eGFR (60–89 ml/min per 1.73 m 2) | 1,089 (18.21) |
| Moderately reduced eGFR (30–59 ml/min per 1.73 m 2) | 91 (1.52) |
| Severely reduced eGFR (15–29 ml/min per 1.73 m 2) | 4 (0.07) |
| Kidney Failure (eGFR <15 ml/min per 1.73 m 2) | 3 (0.05) |
*The CKD-EPI eGFR calculations were used as the primary outcomes in this study; the MDRD equation was used to contrast the difference between the two equations. 1The coefficient for black race was omitted while using this equation.
