The number of induced abortions was estimated by subtracting the number of live births, stillbirths, miscarriages and ectopic pregnancies from total number of pregnancies.

Age at which participant went through menopause. Computed using Form 31, questions 5, 6.1, 10, 10.1; Form 2, questions 7, 18, 18.2; Form 43 (age first used HRT).  See [Menopause Algorithm](https://www.whi.org/doc/Algorithm-Age-at-Menopause.pdf) for detail on how this is computed.
