The assessed parameters for change from baseline were QALY scores. The methodology used for the analysis of the SF-36v2 questionnaire was detailed in Ware et al \[Ware 2008\]. The QualityMetric Health Outcomes Scoring Software was used to generate a Quality of Life analysis dataset based on the SF-36 questionnaire. QoL data were transformed to generate Quality-Adjusted Life Years (QALY) scores. A standard algorithm was developed for processing subjects' answers and producing QALY scores. For all subscale components, scores range from 0 to 100, with high scores indicating high levels of functio
