Lp(a) quintile levels were derived from the stratum of women not taking hormone replacement therapy.
Framingham-adjusted model refers to adjustments for covariates age, blood pressure categories, current smoking status, total cholesterol and high-density lipoprotein values.
Fully-adjusted models refer to Framingham covariates of age, blood pressure categories, current smoking status, total cholesterol and high density lipoprotein values as well as body mass index, diabetes, C-reactive protein and treatment arms.
Lp(a) quintile levels were derived from women not taking hormone replacement therapy.
Median LDL-C value was 121.4 mg/dL.
