When the calculated LDL-C was < 40 mg/dL or triglycerides were > 400 mg/dL, calculated LDL-C was replaced with ultracentrifugation LDL-C from the same blood sample, if available.
Adjusted p value is based on a combination of sequential testing, the Hochberg procedure, the fallback procedure to control the overall significance level for all primary and secondary endpoints. Each individual adjusted p value is compared to 0.05 to determine statistical significance.
Repeated-measures model, which includes treatment group, stratification factor of screening LDL-C level (from IVRS), scheduled visit, and the interaction of treatment with scheduled visit as covariates.
Least significant unadjusted p value of the co-secondary endpoints, using the repeated-measures model.
The unadjusted joint p value using the union-intersection test.
Abbreviations: ApoB, apolipoprotein B; HDL-C, high-density lipoprotein-cholesterol; IVRS, interactive voice response system; LDL-C, low-density lipoprotein-cholesterol; Lp(a), lipoprotein(a).
