a Each final longitudinal model included obligatory variables: treatment (control versus combined treatment with 80 mg or 120 mg of isoflavones), time point (baseline versus 12, 24, or 36 months), treatment by time point interaction, and site (ISU versus UCD), as well as potential covariates that included androidal fat mass (kg) adjusted for height, time since last menstrual period (TLMP), family history of CVD (Fam Hx) coded as a categorical variable (none versus positive or none versus unknown), and Healthy Eating Index (HEI) score. This table shows only those covariates that were significant ( 𝑃 . 0 5 ) for each outcome variable or had a tendency ( 𝑃 . 1 0 ) to be significant.
b The likelihood ratio for each model represents the ratio of a model that includes only obligatory variables compared to the final model that includes obligatory variables and covariates. The overall P value for each model was ≤.0001, except the LDL model had a P value = . 0 0 2 8 .
