Correlation between renal function at vascular access (VA) creation and estimated glomerular filtration rate (eGFR) slope by VA created timely or not timely (n = 763). Renal function expressed by creatinine (Cr) (a), estimated glomerular filtration rate (eGFR) by modification of diet in renal disease (MDRD) (b) calculated by the equation: 186 \(\times\) serum creatinine−1.154 \(\times\) age−0.203 \(\times\) 1.212 (if patient is black) \(\times\) 0.742 (if female)22, and eGFR by Cockcroft–Gault (CG) (c) calculated by the equation: [(140 − age)] \(\times\) weight \(\times\) 0.85 (if female)/(72 \(\times\) serum creatinine), adjusted for BSA/1.73 m2. \(BSA = weight~_{{{\text{kg}}}}^{{0.425}} \times height~_{{{\text{cm}}}}^{{0.725}} \times 0.007184\)23.
