A. Pairwise comparisons of values at study end between women randomized to HT and those randomized to placebo within each metabolic phenotype. Data are presented as estimate (95% confidence interval). B. Cluster by treatment interaction effect on the study end values of the nine metabolic biomarkers and three cognitive composite scores.
