Adjusted for age at interview, site and maternal education; P for interaction of menopausal transition = 0.28; P for interaction of natural menopause = 0.65; P for interaction of combined = 0.26.
b
Adjusted for age at interview, site and maternal education; P for interaction of menopausal transition = 0.29; P for interaction of natural menopause = 0.47; P for interaction of combined = 0.24.
