Kaplan–Meier curves of the relationship between the resistance index (RI) at 7 days after surgery and the patency rate in the early or late cannulation groups. (a) In the early cannulation group, patients with an RI of <0.65 (solid line; n = 66) had a significantly higher patency rate than did patients with an RI of ≥0.65 (dotted line; n = 11) (P < 0.001∗). (b) In the late cannulation group, RI did not affect the patency rate (patients with an RI of <0.65: solid line, n = 18; patients with an RI of ≥0.65: dotted line, n = 8) (P = 0.36).
