Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Change in Body Weight (%)	Observed mean change in body weight from baseline (week 0) to week 56 was evaluated for two different observation periods. In-trial observation period: the uninterrupted time interval from the date of randomisation until and including the date of the follow-up visit or date of last contact. On-drug observation period: includes all time intervals in which subjects are considered to be on treatment from the date of first trial product administration to 7 days (or 14 days for AEs) after the final trial product administration, excluding potential off-treatment time intervals triggered by at least 7 consecutive missed doses (or 14 consecutive missed doses for AEs).; The test of superiority of liraglutide to placebo for the treatment policy estimand was tested in a hierarchical manner for the two primary and the consequent 7 confirmatory secondary endpoints presented.	Week 0, week 56
Primary	Proportion of Subjects Losing at Least 5% of Baseline Body Weight at Week 56	The estimated mean percentage of subjects losing at least 5% of baseline body weight at week 56 is presented. The endpoint was evaluated based on in-trial data and on-drug data.	Week 56
Secondary	Proportion of Subjects Losing More Than 10% of Baseline Body Weight at Week 56	The estimated mean percentage of subjects losing more than 10% of baseline body weight at week 56 is presented. The endpoint was evaluated based on in-trial data and on-drug data.	Week 56
Secondary	Proportion of Subjects Losing More Than 15% of Baseline Body Weight at Week 56	The estimated mean percentage of subjects losing more than 15% of baseline body weight at week 56 is presented. The endpoint was evaluated based on in-trial data and on-drug data.	Week 56
Secondary	Proportion of Subjects Losing 4% or More of Baseline Body Weight	The estimated mean percentage of subjects losing 4% or more of baseline body weight at week 16 is presented. The endpoint was evaluated for treatment policy estimand (in-trial data).	Week 16
Secondary	Change in Waist Circumference (cm)	Observed mean change from baseline in waist circumference. The endpoint was evaluated based on in-trial data and on-drug data.	Week 0, week 56
Secondary	Change in Short Form-36 (SF-36) v2.0 Acute, Physical Functioning Score	SF-36 is a 36-item patient-reported survey of patient health that measures the subject's overall health-related quality of life (HRQoL).; SF-36v2™ questionnaire measured the HRQoL on 8 domains on individual scale ranges.

A norm-based score of 50 corresponds to the mean score and 10 corresponds to the standard deviation of the 2009 U.S. general population. Change from baseline in SF-36 physical functioning score is presented. A positive change score indicates an improvement since baseline.
