Table 3 Comparison of predictive equations during follow-up in CKD patients with non-diabetic nephropathies.
Method of GFR estimation | Slope of GFR (ml/min/1.73 m2/year) Median and [range] | p value in the Friedman test (non parametric ANOVA) | P value in Dunn's multiple comparison post-test | |

GFR Cockcroft-Gault | -4.08 [-0.36 to -60] | NS | ||
BSA-modified Cockcroft-Gault Formula | -3.48 [-0.24 to -56] | p = 0.29 | NS | |
Abbreviated MDRD equation | -3.12 [0 to -64] | NS | ||
Mayo Clinic Quadratic equation | -3.73 [0 to -78] | NS | ||
