SF-36 is a standardized survey evaluating 8 aspects of functional health and well being: physical functioning, role physical, bodily pain, general health, vitality, social functioning, role emotional and mental health. The score for a section is an average of the individual question scores, which are scaled 0-100 (100=highest level of functioning) and was reported as 2 summary scores; Physical Component Score and Mental Component Score. Total score range for the summary scores = 0-100 where higher scores represented higher level of functioning.

FACIT-Fatigue scale is a 13-item questionnaire. Participant scored each item on a 5-point scale: 0 (Not at all) to 4 (Very much). The larger the participant's response to the questions (with the exception of 2 negatively stated), the greater the fatigue. For all questions, except for the 2 negatively stated ones, the code was reversed and a new score was calculated as 4 minus the participant's response. The sum of all responses resulted in the FACIT-Fatigue score for a total possible score of 0 (worse score) to 52 (better score). A higher score reflected an improvement in the participant's health status.

Participant-rated questionnaire to assess key constructs of sleep over the past week. Consists of a 12-item based on 7 sub scales: sleep disturbance (SD), snoring (Sno), awakened short of breath (ASOB) or with headache, sleep adequacy (Ade), and somnolence (Som) (range:0-100); sleep quantity (Qua)(range:0-24), and optimal (Opt) sleep (yes: 1, no: 0) and nine item index measures of sleep disturbance were constructed to provide composite scores: sleep problem summary (SPS) and overall sleep problems (OSP). Except sleep adequacy, optimal sleep and quantity, higher scores=greater impairment. Scores are transformed (actual raw score minus lowest possible score divided by possible raw score range* 100); total score range: 0 to 100; higher score = greater intensity of attribute.

EQ-5D: participant rated questionnaire to assess health-related quality of life in terms of a single utility score. Health State Profile component assesses level of current health for 5 domains: mobility, self-care, usual activities, pain and discomfort, and anxiety and depression; 1 indicates better health state (no problems); 3 indicates worst health state ("confined to bed"). Scoring formula developed by EuroQol Group assigns a utility value for each domain in the profile. Score is transformed and results in a total score range -0.594 to 1.000; higher score indicates a better health state.
