Percent Change From Baseline in Lp(a) - Assessed Via Intact Lp(a) Assay
Least Squares Mean (LS Mean) was calculated using a Mixed Model for Repeated Measures (MMRM): Log (Actual Measurement/Baseline) = Log (Baseline) + Country + Treatment + Time + Treatment\*Time.
Time frame: Baseline, Week 12
Percent Change From Baseline in Lp(a) - Assessed Via Apo(a) Assay
LS Mean was calculated using a MMRM: Log (Actual Measurement/Baseline) = Log (Baseline) + Country + Treatment + Time + Treatment\*Time.
Time frame: Baseline, Week 12
Percentage of Participants Who Achieved Lp(a) < 125 Nmol/L - Assessed Via Intact Lp(a) Assay
The percentage of participants who achieved Lp(a) less than (\<) 125 nmol/L, as measured using the intact Lp(a) assay, with data analysis performed through a logistic regression model that included imputed missing values, was reported.
Time frame: Week 12
Percentage of Participants Who Achieved Lp(a) < 125 Nmol/L - Assessed Via Apo(a) Assay
The percentage of participants who achieved Lp(a) \< 125 nmol/L, as measured using the apo(a) assay, with data analysis performed through a logistic regression model that included imputed missing values, was reported.
Time frame: Week 12
Percent Change From Baseline in Apolipoprotein B (ApoB)
LS Mean was calculated using a MMRM: Log (Actual Measurement/Baseline) = Log (Baseline) + Country + Baseline Lp(a) Stratum + Treatment + Time + Treatment\*Time.
Time frame: Baseline, Week 12
Percent Change From Baseline in High-Sensitivity C-Reactive Protein (hsCRP)
LS Mean was calculated using a MMRM: Log (Actual Measurement/Baseline) = Log (Baseline) + Country + Baseline Lp(a) Stratum + Treatment + Time + Treatment\*Time.
Time frame: Baseline, Week 12
Pharmacokinetics (PK): Trough Concentrations (C-trough) of LY3473329
C-trough were measured at specified time points to assess the minimum concentration of LY3473329 in the blood before the next dose was administered.
