Primary Outcome Measures
NameTimeMethod
Mean Percent Change From Baseline in Body WeightBaseline, Week 24

Least squares (LS) means were calculated using a mixed-effects model for repeated measures (MMRM) for post-baseline measures: Variable = Treatment\*Time + Baseline BMI (\< 36kg/m2 vs. \>=36 kg/m2)\*Time + Sex (Female vs. Male)\*Time + Baseline\*Time.

Secondary Outcome Measures
NameTimeMethod
Mean Percent Change From Baseline in Body WeightBaseline, Week 48

LS means were calculated using a MMRM model for post-baseline measures: Variable = Treatment\*Time + Baseline BMI (\< 36kg/m2 vs. \>=36 kg/m2)\*Time + Sex (Female vs. Male)\*Time + Baseline\*Time.

Percentage of Participants Who Achieve ≥ 5% Body Weight ReductionWeek 48

Percentage of participants who achieve ≥ 5% body weight reduction in LY3437943 relative to placebo. Estimated percentage was determined by logistic regression model with an intercept term, treatment group, baseline BMI stratum \[\<36 kg/m2, ≥36 kg/m2\] and sex \[female, male\] as fixed effects, and baseline body weight as a covariate.

Percentage of Participants Who Achieve ≥ 10% Body Weight ReductionWeek 48

Percentage of participants who achieve ≥ 10% body weight reduction in LY3437943 relative to placebo. Estimated percentage was determined by logistic regression model with an intercept term, treatment group, baseline BMI stratum \[\<36 kg/m2, ≥36 kg/m2\] and sex \[female, male\] as fixed effects, and baseline body weight as a covariate.

Percentage of Participants Who Achieve ≥ 15% Body Weight ReductionWeek 48

Percentage of participants who achieve ≥ 15% body weight reduction in LY3437943 relative to placebo. Estimated percentage was determined by logistic regression model with an intercept term, treatment group, baseline BMI stratum \[\<36 kg/m2, ≥36 kg/m2\] and sex \[female, male\] as fixed effects, and baseline body weight as a covariate.
