PF: Physical function, SE: Self-esteem, SL: Sexual life, PD: Public distress, WO: Work, TT: Total (the higher scores reflect a better quality of life).

* P<.05, †P<.01, ‡P<.001, these P-values refer to the significance of the difference between the quality of life score of the specific population as compared to the quality of life of all other populations.
