- Patients with a follow-up shorter than 3 months were excluded. The model was adjusted for all variables in Table 1 as well as region, year of hemodialysis initiation, and vascular access changes as time dependent variable. Abbreviations: AV arteriovenous, HR hazard ratio, CI confidence interval
- Adjusted mortality hazard ratios associated with initial vascular access taking subsequent changes into account
