SF-36 is a 36-item patient-reported survey of patient health that measures the participant's overall health-related quality of life (HRQoL). SF-36v2™ (acute version) questionnaire measured eight domains of functional health and well-being as well as two component summary scores (physical component summary (PCS) and mental component summary (MCS)). The 0-100 scale scores (where higher scores indicated a better HRQoL) from the SF-36 were converted to norm-based scores to enable a direct interpretation in relation to the distribution of the scores in the 2009 U.S. general population. In the metric of norm-based scores, 50 and 10 corresponds to the mean and standard deviation respectively of the 2009 U.S. general population. Change from baseline (week 0) in the sub-domain scores and component summary (PCS and MCS) scores were evaluated at week 26. A positive change score indicates an improvement since baseline. Results are based on the data from the in-trial observation period.
