Figure 4.

Associations between type of access and access complications. Cox model stratified by complication type and adjusted for all clinical characteristics described in Table 1 (analysis with multiply imputed data; n=6119). The model accounts for the correlation among repeated complications of different types in the same person (325 participants). The corresponding model including only participants with complete data (n=5722), showing similar results, is reported in Supplemental Figure 2; other sensitivity analyses are reported in Supplemental Figures 3–5. The parenthetical indications <90 and 90–180 days refer to noninfectious complications occurring during the first 90 days since access creation and after, respectively. 95% CI, 95% confidence interval; HR, hazard ratio.
