Associations of menopausal status and age at natural menopause with diabetes risk. Specifically, A for menopausal status; B for age at natural menopause among post-menopausal women only. Squares represent the adjusted hazard ratios (HRs) compared with the reference group of pre-menopausal status (A) and menopause at age 45–49 years (B), respectively, with area inversely proportional to the number of cases. Vertical lines indicate the corresponding 95% confidence intervals (CIs)
