Notes. aThe Peds-QL 4.0 [23] was developed for children between the ages of 8-12. The maximum possible score on each of the subscales is 100. Two participants were removed from the QOL analyses as they were not in this age range.
bOne child was removed from the body composition analyses because s/he was on a prescribed medication that is known to contribute to weight gain.
*Statistically significant change from baseline.
