Results are shown as the mean ± standard deviation change from baseline to study endpoint.
^a p-values based on analysis of covariance model controlling for country of origin, age, body mass index (BMI), years since menopause, smoking status (yes vs. no), alcohol consumption (yes vs. no), and number of preexisting conditions.
