Kaplan–Meier survival curves for graft failure by using the cutoff of the eGFR-CV of serially measured eGFR values in all patients (A) and in patients without AR (B).

<p>Black and gray lines indicate the cutoff of eGFR-CV (black: higher-CV, gray: lower-CV). eGFR: estimated glomerular filtration rate; AR: acute rejection; CV: coefficient of variation of eGFR; higher-CV: higher values than the cutoff of eGFR-CV; lower-CV: lower values than the cutoff of eGFR-CV.
