Decrements in HRQOL were most predominant in general health perception and role limitations caused by emotional health problem, with scores of 33.5 + 16.9, 40.8 +/- 25.1 respectively. The emotional well-being and energy/fatigue scale scores were also quite low (42.2 +/- 19.3,43.1 +/- 20.2,respectively).
