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 analysed by analysis of covariance (ANCOVA) model with randomization + analysis Country + sex + weight loss at Week 36 (\< 10%, \>= 10%) + IWRS MTD at Week 36 + treatment (type III sum of squares) as variables., Randomization (Week 36), Week 88|Change From Randomization 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 analysed by ANCOVA model with randomization + analysis Country + sex + weight loss at Week 36 (\< 10%, \>= 10%) + IWRS MTD at Week 36 + treatment (type III sum of squares) as variables., Randomization (Week 36), Week 88|Percentage of Participants Who Maintain at Least 80% of the Body Weight Lost During the Open-Label Lead-In Period, Percentage of Participants Who Maintain at least 80% of the Body Weight Lost During the Open-Label Lead-In Period was analysed by Logistic regression model with missing value imputed by MMRM at week 88.
