Figure 1From: MDRD or CKD-EPI study equations for estimating prevalence of stage 3 CKD in epidemiological studies: which difference? Is this difference relevant? Bland and Altman analysis between the MDRD study equation and the new CKD-EPI equations. The continuous line represents the mean difference between estimated GFRs, whereas the dashed lines represent the limits of agreement (mean difference ± 2SD). All values are expressed in mL/min/1.73 m2.Back to article page
