Abbreviations: CI, confidence interval; IQR, interquartile range; RR, risk ratio.
a Comparison between patients with recurrence and those without recurrence.
b Creatinine conversion: 1 μmol/L is equal to 0.0113 mg/dL. Therefore, 133 μmol/L is equal to 1.50 mg/dL.
c Data are no. of patients with recurrence/overall no.
d For the association with recurrence.
