*Group-by-group comparisons that were significant at the level of P < 0.001 performed using LSD (homogenous variance; used for physical and overall quality of life) or Dunnet T3 (unhomogenous variance; all other questions). The significance was set at P < 0.001 in post-hoc test in order to reduce the increased chances of false positive results.
