Mean Change From Baseline in High Density Lipoprotein (HDL) Cholesterol (Pooled Doses of Tirzepatide 10 mg and 15 mg)Baseline, Week 52

LS mean was determined using MMRM model using log (Actual Measurement) = log (Baseline) + Sex + Presence of comorbidities + Treatment + Time + Treatment\*Time (Type III sum of squares) as variables.

Mean Change From Baseline in Low Density Lipoprotein (LDL) Cholesterol (Pooled Doses of Tirzepatide 10 mg and 15 mg)Baseline, Week 52

LS mean was determined using MMRM model with Baseline + Sex + Presence of comorbidities + Treatment + Time + Treatment\*Time (Type III sum of squares) as variables.

Mean Change From Baseline in Triglycerides (Pooled Doses of Tirzepatide 10 mg and 15 mg)Baseline, Week 52

Mean Change From Baseline in Fasting Insulin (Pooled Doses of Tirzepatide 10 mg and 15 mg)Baseline, Week 52

Mean Change From Baseline in Short-Form-36 Health Survey Version 2 (SF-36v2) Acute Form Physical Functioning Domain ScoreBaseline, Week 52

The SF-36v2 acute form, 1-week recall assesses participants' 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. Information from these 8 domains is further aggregated into 2 health component summary scores: Physical Component Summary and Mental Component Summary.

Items are answered on Likert scales of varying lengths. Scoring of each domain and both summary scores are 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 and/or better health. Range cannot be specified in norm-based scores.

LS mean was determined using analysis of covariance (ANCOVA) model using Baseline + Sex + Presence of comorbidities + Treatment (Type III sum of squares) as variables.

Mean Change From Baseline in Impact of Weight on Quality of Life-Lite Clinical Trials Version (IWQOL-Lite-CT) Physical Function Composite ScoreBaseline, Week 52

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. Total score of IWQOL-Lite-CT composite ranges from 0 to 100, with higher scores reflecting better quality of life. LS mean was determined using ANCOVA model with Baseline + Sex + Presence of comorbidities + Treatment (Type III sum of squares) as variables.
