TLDR
Of the many factors examined that might affect the relation between breast cancer risk and use of HRT, only a woman's weight and body-mass index had a material effect: the increase in the relative risk of breast cancer diagnosed in women using HRT and associated with long durations of use in current and recent users was greater for women of lower than of higher weight or body- mass index.

Risks and benefits of estrogen plus progestin in healthy postmenopausal women: Principal results from the Women's Health Initiative randomized controlled trial

TL;DR: Overall health risks exceeded benefits from use of combined estrogen plus progestin for an average 5.2-year follow-up among healthy postmenopausal US women, and the results indicate that this regimen should not be initiated or continued for primary prevention of CHD.

Randomized Trial of Estrogen Plus Progestin for Secondary Prevention of Coronary Heart Disease in Postmenopausal Women

TL;DR: Treatment with oral conjugated equine estrogen plus medroxyprogesterone acetate did not reduce the overall rate of CHD events in postmenopausal women with established coronary disease and the treatment did increase the rate of thromboembolic events and gallbladder disease.

Design and analysis of randomized clinical trials requiring prolonged observation of each patient. II. analysis and examples.

TL;DR: Efficient methods of analysis of randomized clinical trials in which the authors wish to compare the duration of survival among different groups of patients are described.

Design and analysis of randomized clinical trials requiring prolonged observation of each patient. I. Introduction and design.

TL;DR: This report is the first simple account yet published for non-statistical physicians of how to analyse efficiently data from clinical trials of survival duration, and it may be preferable to use these statistical methods to study time to local recurrence of tumour, or toStudy time to detectable metastatic spread, in addition to studying total survival.

The use of estrogens and progestins and the risk of breast cancer in postmenopausal women.

TL;DR: In this paper, the effect of adding progestins to estrogen therapy on the risk of breast cancer in postmenopausal women is investigated. But, the effect on the number of newly diagnosed invasive breast cancer cases was not quantified.

Canadian National Breast Screening Study: 1. Breast cancer detection and death rates among women aged 40 to 49 years

TL;DR: Screening with yearly mammography and physical examination of the breasts detected considerably more node-negative, small tumours than usual care, but it had no impact on the rate of death from breast cancer up to 7 years' follow-up from entry.
