Arteriovenous fistula (AVF) patency rate in patients with an intima-media thickness (IMT) ≥ 500 µm (n = 26) or < 500 µm (n = 64). Five patients who died with a patent AVF before the study end point were included as censored data. p = 0.017 vs. the patent group by the Kaplan-Meier method and log-rank test. Adapted from Kim et al. [33].
