Variability in Estimated Glomerular Filtration Rate by Area under the Curve Predicts Renal Outcomes in Chronic Kidney Disease

Figure 2

Two representative cases to illustrate the eGFR variability. In Case 1, the initial eGFR AUC%_12M (a) and peak eGFR AUC%_12M (b) were 85.0% and 68.9%, respectively. The eGFR slope of Case 1 was −1.06 mL/min/1.73 m² per month. In Case 2, the initial eGFR AUC%_12M (c) and peak eGFR AUC%_12M (d) were 64.8% and 51.3%, respectively. The eGFR slope of Case 2 was −1.51 mL/min/1.73 m² per month. Case 2 had greater eGFR variability than that of Case 1.
