  1. Data are presented as median, mean and standard deviation (SD) of PedsQL scores
  2. P-values derived from the chi-squared (χ2) or Wilcoxon tests
  3. PedsQL Pediatric Quality of Life Inventory 4.0. Higher score means better quality of life. Possible range of PedsQL scores is from 0 to 100
  4. Disease duration was dichotomized using the sample mean rounded to the nearest integer as the cut point
