a Bias in function of CrCl24h for the three formulae estimating renal function. Top: MDRD (ml/min/1.73 m2); mid: CG corrected for a body surface area of 1.73 m2 (ml/min/1.73 m2); bottom: CKD-EPI (ml/min/1.73 m2). b Receiver operating characteristics curve analysis for the CKD-EPI formula. The shaded area represents the 95% confidence intervals. The dots represent the cut-off values for optimized sensitivity and specificity, very high (> 95%) sensitivity and very high (> 95%) specificity
