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

Table 1

Different methods to estimate variability of eGFR.

Method	Definition of calculation
(A) Initial eGFR AUC%_12M	Initial eGFR is baseline value and estimated variability of eGFR during 12 months (gray area was divided into rectangle area)
(B) Peak eGFR AUC%_12M	Peak eGFR is baseline value and estimated variability of eGFR during 12 months (gray area was divided into rectangle area)

eGFR: estimated glomerular filtration rate; AUC: area under the curve.
