Comparison of the survival rate between patients whose estimated glomerular filtration rate (eGFR) was <30 ml/min/1.73 m² and other patients in the elderly and nonelderly groups. (a) Elderly group. The mean survival time periods were 36.3 ± 7.9 and 78.2 ± 6.1 months among patients whose eGFR was <30 ml/min/1.73 m² and among other patients, respectively (, log-rank test). (b) Nonelderly group. The mean survival time periods were 35.7 ± 5.0 and 124.1 ± 2.6 months among patients whose eGFR was <30 ml/min/1.73 m² and among other patients, respectively (, log-rank test).
