Table 3. Partial correlations of difference between GFR estimates obtained with MDRD, CKD-EPI, BIS1 equations and equation related factors (age and serum creatinine).
| Δ(MDRD, CKD-EPI) | Δ(MDRD, BIS1) | Δ(CKD-EPI, BIS1) | ||||
|---|---|---|---|---|---|---|
| Partial correlation coefficient | Partial R2 | Partial correlation coefficient | Partial R2 | Partial correlation coefficient | Partial R2 | |
| Age (years) | 0.376* | 14.138% | 0.419* | 17.556% | 0.025 | 0.063% |
