Therefore, the total and subdomain scores on the IWQoL-Lite could not be provided.
Change in SF-36
Short Form-36 (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 domain scores and component summary (PCS and MCS) scores were evaluated at week 52. A positive change score indicates an improvement since baseline. Results are based on the in-trial observation period.
