Secondary	Change From Baseline in Short Form 36 Version 2 Health Survey Version 2 (SF 36v2) Acute Form Physical Functioning Domain Score	The SF-36v2 acute form assesses health-related quality of life (HRQoL) on 8 domains: Physical Functioning, Role-Physical, Bodily Pain, General Health, Vitality, Social Functioning, Role-Emotional, and Mental Health. The Physical-Functioning domain assesses limitations due to health "now" and consists of 10-items, each rated on a 3-point Likert scale. Scoring of the domain is norm-based and presented in the form of T-scores, with a mean of 50 and standard deviation of 10; higher scores indicate better levels of function. Range cannot be specified in norm-based scores.; LS mean was determined using analysis of covariance (ANCOVA) model using Baseline + Analysis Country + Sex + Lead-In Weight Loss % + Treatment (Type III sum of squares) as variables.	Baseline, 72 Weeks
Secondary	Change From Baseline in Impact of Weight on Quality of Life Lite Clinical Trials Version (IWQOL-Lite-CT) Physical Function Composite Score	The IWQOL Lite-CT consists of 20 items, assessing 2 primary domains of obesity related HRQoL: Physical (7 items) and Psychosocial (13 items). A 5-item subset of the Physical domain - the Physical Function composite - is also supported. Items in the Physical Function composite describe physical impacts related to general and specific physical activities. All items in the physical domain are rated on either a 5-point frequency ("never" to "always") scale or a 5-point truth ("not at all true" to "completely true") scale. Total score of IWQOL-Lite-CT composite ranges from 0 to 100, with higher scores reflecting better health-related quality of life.; LS mean was determined using ANCOVA model with Baseline + Analysis Country + Sex + Lead-In Weight Loss % + Treatment (Type III sum of squares) as variables.	Baseline, 72 Weeks
