Figures & data
Figure 1. Bland–Altman plots of difference versus average of the MDRD and the CKD-EPI formulas in women and men. Solid lines show mean differences and dotted lines 95% limits of agreement. (eGFR = estimated glomerular filtration rate; CKD-EPI = Chronic Kidney Disease Epidemiology Collaboration; MDRD = Modification of Diet in Renal Disease).
