1.Primary Outcome
Title Percent Change From Baseline (PCFB) in Low-density Lipoprotein Cholesterol (LDL-C) at Week 12
Hide Description PCFB was calculated as the ([post-Baseline (BL) value minus the BL value] divided by the BL value ) x 100. BL was defined as the mean of the last two non-missing values on or prior to Day 1. If only one value was available, that single value was used as BL. PCFB in LDL-C was analyzed using analysis of covariance (ANCOVA), with treatment group and stratification factor (primary prevention; secondary prevention) as fixed effects and BL as a covariate. For participants with missing lipid data at Week 12 who were no longer taking study treatment, missing values were imputed using multiple imputation via a regression-based model including stratification and BL data from placebo participants only. In this imputation model, treatment group was not included. For participants with missing lipid data at Week 12 who were still taking study treatment, missing values were imputed using multiple imputation via a regression-based model including treatment, stratification and BL value.

Hide Analysis Population Description
The Full Analysis Set (FAS), also known as the intention-to-treat (ITT) set of participants, is defined as all randomized participants. Participants were included in their randomized treatment group, regardless of the treatment they actually received. Only those participants with available data were analyzed.

If only one value was available then that single value was used as BL.

3.Secondary Outcome
Title Percent Change From Baseline in the Lipid Profile at Week 12
Hide Description PCFB was calculated as: ([post-BL value minus the BL value] divided by the BL value) x 100. BL was defined as the mean of the last two non-missing values on or prior to Day 1. If only one value was available, that single value was used as BL. apoB and TC BL were defined as the last non-missing value on/prior to Day 1. PCFB was analyzed using ANCOVA, with treatment and group stratification factor (primary prevention; secondary prevention) as fixed effects and BL as a covariate. For participants with missing data at Week 12 who were no longer taking study treatment (ST), missing values were imputed using multiple imputation via a regression-based model including stratification and BL data from placebo participants only. In this imputation model, treatment group was not included. For participants with missing lipid data at Week 12 who were still taking ST, missing values were imputed using multiple imputation via a regression-based model including treatment, stratification and BL value.
