Figure 1 Bland-Altman plots of the difference between the first- and second-examination values plotted against the mean of (A) measured creatinine, (B) estimated glomerular filtration rate using the MDRD (Modification of Diet in Renal Disease) Study equation, (C) estimated glomerular filtration rate using the CKD-EPI (Chronic Kidney Disease Epidemiology Collaboration) creatinine 2009 equation, (D) measured cystatin C, (E) estimated glomerular filtration rate using the CKD-EPI cystatin 2012 equation, (F) measured β2-microglobulin, (G) measured β-trace protein, (H) log-transformed urinary albumin, and (I) log-transformed albumin-creatinine ratio (ACR). The solid line represents the mean difference; dashed lines represent the mean ± 2 standard deviations.
