Serial changes in sCr concentration and estimated glomerular filtration rate in kidney transplant donors and recipients one year after transplantation. (a) Among donors, postoperative sCr concentrations were significantly higher in the control than in the RIPC group on postoperative days (PODs) zero (0.9 mg/dL, 95% CI: 0.86–0.95 mg/dL vs. 0.83 mg/dL, 95% CI: 0.79–0.87 mg/dL, p = 0.024), two (1.18, 95% CI: 1.12–1.24 mg/dL vs. 1.06, 95% CI: 1.00–1.12, p = 0.005), discharge day (1.13, 95% CI: 1.07–1.18 mg/dL vs. 1.01, 95% CI: 0.97–1.07, p = 0.003), one month (1.08, 95% CI: 1.03–1.13 mg/dL vs. 1.01, 95% CI: 0.96–1.06, p = 0.043), and 12 months (1.06, 95% CI: 1.01–1.11 mg/dL vs. 0.97, 95% CI: 0.92–1.02, p = 0.015). (b) Among donors, estimated glomerular filtration rate (eGFR) was calculated using the CKD-EPI equation. eGFR was not significantly different in the control and the RIPC groups. (c) Among recipients, sCr concentration did not differ in the RIPC and control groups at any time point. (d) Estimated glomerular filtration rate (eGFR) was calculated using the Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI) equation. Among recipients, eGFR was not different between in the RIPC and control groups at any time point.
