Mean differences between baseline and 12 weeks in the placebo and pooled active treatment groups. (a) Arterial stiffness. (b) Central blood pressure (BP). ET, estrogen therapy; EPT, estrogen + progestogen therapy; PWV, brachial–ankle pulse-wave velocity; AIx, augmentation index; cAIx, corrected augmentation index at a heart rate of 75 bpm; SBP, systolic BP; DBP, diastolic BP; PP, pulse pressure; I bars indicate standard errors. There was no significant difference between groups. ^aP-value for within-group difference between baseline and 12 weeks of treatment < 0.05, by the signed -rank test
