  1. * Using the 0-100% scoring method: Mean (SD) [95% Confidence Intervals]
  2. * In all domains and for both sexes, quality of life decreased with age, such that those aged 14-15 and 16-17 had significantly higher scores than those aged 18-19 and 20-23: KWχ2 = 13.9 - 93.4, df = 3, P < 0.001..
  3. ** In all domains, males had significantly higher QOL than females: Mann-Whitney U = 1859917 - 2262080, Z = 5.2 - 11.6, P < 0.0001.
  4. *** Adjusted for age, father's occupation, depression and anxiety scores.
