  1. 1CHQ scores and PedsQL™4.0 range from 0 (worst possible score) to 100 (best possible score) with higher scores representing a better quality of life. BES scores range from 0 (worst possible score) to 4 (best possible score), with higher scores representing a better body esteem.
  2. 2The numbers of subjects varied at 6 months from 44–45 in the intervention group and from 33–34 in the control group. After the 18 month follow-up the numbers of subjects varied in the intervention group between 34–35 and in the control group from 23–28.
