Financial 1.01 (0.96 - 1.05) 0.78
  1. • HRs correspond to a 10-point increment for QoL scores
  2. • 2 sets of multivariate models were constructed: one for global QoL and other for all general function and symptom variables combined
  3. • Multivariate model (for change in general function and symptom variables combined) adjusted for age, gender, stage at diagnosis, prior treatment history and all QoL change variables excepting role function change
  4. • Multivariate model for change in global QoL adjusted for age, gender, stage at diagnosis and prior treatment history
  5. • *P < 0.05
