ListOutcomeTime frameDescription
PrimaryPercent Change From Baseline in Body Weight (Primary Treatment Period)Baseline, Week 72
Least Squares (LS) Mean was calculated using mixed-model repeated measures (MMRM) with baseline, analysis country, sex, prediabetes status at randomization, treatment, time, treatment\*time (Type III sum of squares) in the model.
PrimaryPercentage of Participants Who Achieve ≥5% Body Weight Reduction (Primary Treatment Period)Week 72Percentage of participants who achieve greater than or equal to( ≥) 5% body weight reduction.
SecondaryChange From Baseline in Body Weight (Pooled Doses of Tirzepatide 10 mg and 15 mg) - Primary Treatment PeriodBaseline, Week 20LS Mean was calculated using MMRM with baseline, analysis country, sex, prediabetes status at randomization, treatment, time, treatment\*time (Type III sum of squares) in the model.
SecondaryPercentage of Participants Who Achieve ≥10% Body Weight Reduction (Primary Treatment Period)Week 72Percentage of Participants who Achieve ≥10% Body Weight Reduction
SecondaryPercentage of Participants Who Achieve ≥15% Body Weight Reduction (Primary Treatment Period)Week 72Percentage of participants who achieve ≥15% body weight reduction.
SecondaryPercentage of Participants Who Achieve ≥20% Body Weight Reduction (Primary Treatment Period)Week 72Percentage of participants who achieve ≥20% body weight reduction.
SecondaryChange From Baseline in Waist Circumference (Primary Treatment Period)Baseline, Week 72LS Mean was calculated using MMRM with baseline, analysis country, sex, prediabetes status at randomization, treatment, time, treatment\*time (Type III sum of squares) in the model.
SecondaryChange From Baseline in Short Form Survey-36 Version 2 (SF-36v2) Acute Form Physical Functioning Domain Score at Week 72 (Pooled Doses of Tirzepatide 10 mg and 15 mg) - Primary Treatment PeriodBaseline, Week 72
The SF-36v2 acute, 1-week recall version is a 36-item, generic, patient-administered measure designed to assess the following 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" while the remaining domains assess functioning "in the past week." Each domain is scored individually and information from these 8 domains are further aggregated into 2 health-component summary scores: Physical-Component Summary and Mental-Component Summary. Items are answered on Likert scales of varying lengths (3-, 5-, or 6- point scales).The summary scores range from 0 to 100, with higher scores indicating better levels of function and/or better health.
SecondaryPercent Change From Baseline in Triglycerides (Pooled Doses of Tirzepatide 5 mg, 10 mg and 15 mg) - Primary Treatment PeriodBaseline, Week 72Percent change from baseline in triglycerides are reported as model-based estimate and Standard Error (SE) from MMRM analysis using log transformation.
SecondaryPercent Change From Baseline in Total Cholesterol (Pooled Doses of Tirzepatide 5 mg, 10 mg and 15 mg) - Primary Treatment PeriodBaseline, Week 72Results are reported as model-based estimate and SE from MMRM analysis using log transformation.
