Comparison of the GFR estimation between 24 hCCr, C-G CCr, eGFR, and urinary tract function status. a: Proportions of cisplatin-eligible and ineligible patients based on the methods used to estimate the GFR. 24hCCr estimation was performed in 188 (77.0%) patients before chemotherapy treatment. The proportion of cisplatin-ineligible patients based on eGFR results was significantly higher than when using 24hCCr using the threshold of 60 mL/min (p = 0.040). The proportion of cisplatin-ineligible patients with a solitary-functioning kidney was significantly higher than those with bilateral-functioning kidneys using both 24hCCr and eGFR tests (p < 0.010 and p < 0.010). b: 24hCCr and eGFR were significantly correlated in patients with bilateral-functioning kidneys (r2 = 0.351, p < 0.001). c: 24hCCr and eGFR were significantly correlated in patients with a solitary-functioning kidney (r2 = 0.402, p < 0.001)
