^aNotes: Menopausal status was coded as a dummy variable: three categories (pre-, peri-, and post-menopausal; men coded as 0 on all the three categories), pre-menopausal is used a reference category.

^bSmoking status was coded as a dummy variable: three categories (never smoked, current smoker, ex-smoker), never smoked is used as a reference category.
