FIG. 1.

The association of estimated glomerular filtration rate (eGFR) with age. The eGFR showed a significantly linear decline with increasing age in both male (A) (R2 linear=0.366, p=0.000) and female (B) (R2 linear=0.434, p=0.000). Dotted lines show the 95% confidence interval (CI). The eGFR was calculated from serum creatinine using the Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI) formula.6 Data are from 1,150 male and 623 female subjects.
