  1. p-Values are from Mann-Whitney or Kruskal-Wallis tests for comparisons across factors with two or three categories, respectively. For patient age, the exact value was correlated with the scores using Spearman’s rho. Bold p-values are significant at p < 0.05
  2. *Excludes N = 2 patients with both CVC and AVF. **For patients where this question was applicable
