Kaplan Meier survival curves comparing long term AVF clinical patency stratified by eGFR (<10 ml/min/1.73 m ² ; 10-15 ml/min/1.73 m ² ; >15 ml/min/1.73 m ² ) and serum urea (<30 mg/dl; 30-40 mg/dl; >40 mg/dl) in patients who were pre-D at the time of AVF creation. A. There was no difference in long-term RCF patency with different eGFR (p = 0.38). B. Long-term patency of RCF was better in patients with lower serum urea at the time of AVF creation (p = 0.01). C. There was no difference in long-term BCF patency with different eGFR (p = 0.61). D. There was no difference in long-term BCF patency depending on serum urea at time of AVF creation (p = 0.79).
