Title: Women's Health Study of Low-dose Aspirin and Vitamin E in Apparently Healthy Women
Brief Summary: The purpose of this study is to evaluate the effects of low-dose aspirin and vitamin E in primary prevention of cardiovascular disease and cancer in apparently healthy women.


Options:
A: Inclusion Criteria:

* Voluntary written informed consent, and who were willing and able to make reasonable efforts to observe all clinical trial requirements were to be enrolled
* Subjects were to be postmenopausal (naturally or surgically) women, from 60 to 85 years of age (inclusive) at entry
* Screening BMD of the total hip and/or spine had to be equal to or lower than 2.5 SD T-score for subjects without an asymptomatic fracture or equal to or lower than -2.0 SD T-score for subjects with an asymptomatic fracture
* Subjects were to have a Body Mass Index (BMI) = 34 kg/m\^2.

Exclusion Criteria:

Subjects with any of the following conditions were not to be enrolled into the trial:

* Recent acute vertebral fracture (diagnosed within the last year) documented by spinal radiograph requiring medication for osteoporosis treatment, in the judgment of the investigator
* More than two prevalent asymptomatic vertebral fractures at baseline
* Screening BMD of the total hip or spine lower than -4 SD T-score
* Unsuitable anatomy on spinal radiographs (lumbar and thoracic vertebrae) e.g., excessive scoliosis
* Not ambulatory
* History or presence of any malignancy within the past five years except for nonmelanoma skin cancer. Subjects with ever history of ovarian cancer or estrogen dependent tumors particularly breast or endometrial cancer were to be excluded
* Trans vaginal ultrasound (TVUS) endometrial double wall thickness \>4 mm
* Unexplained abnormal vaginal bleeding in the past year prior to screening
* Abnormal cervical Papanicolaou (Pap) smear (including low grade squamous intraepithelial lesion (LSIL), high grade squamous intraepithelial lesion (HSIL), atypical squamous cells of undetermined significance (ASCUS), atypical glands of undetermined significance (AGCUS))
* Mammography finding that was suspicious of malignancy
* Bone disease other than osteoporosis such as Paget's disease, osteomalacia, hyperparathyroidism, or bone metastases
* Treatment with anabolic steroids, calcitonin, raloxifene, tamoxifen, or calcitriol within the last six months prior to screening BMD or spinal X-ray measurements.
* Treatment with systemic estrogen and/or progestin within the last three months prior to screening BMD or spinal X-ray measurements (occasional use of estriol containing vaginal cream was allowed)
* Treatment with bisphosphonates for one month or more within the last year
* Ever use of estrogen and/or progestin containing implants

  * Age 35 to 54 with a prior hysterectomy without oophorectomy OR with a status of ovaries unknown with documented follicle-stimulating hormone level demonstrating elevation in postmenopausal range
* Histologically confirmed lobular carcinoma in situ treated by local excision only OR a minimum projected 5 year probability of invasive breast cancer of at least 1.66%, using Breast Cancer Risk Assessment Profile
* No clinical evidence of malignancy on physical exam within the past 180 days
* No evidence of suspicious or malignant disease on bilateral mammogram within the past year
