NAME: The Benign Breast Disease Study KEYWORDS: Logistic Regression SIZE: 200 observations, 14 variables TYPE: Matched Case-Control SOURCE: The data are from Appendix 5 of Hosmer, D.W. and Lemeshow, S. (1989) Applied Logistic Regression, John Wiley and Sons, New York. They are copyrighted and reproduced here with the permission of the publisher. DESCRIPTIVE ABSTRACT: These data contain information from a 1 - 3 matched design studying the risk factors associated with benign breast disease. The data is comprised of a subset of large study in which the original data are from a hospital based case-control study designed to examine the epidemiology of fibrocystic breast disease. Data are provided on 50 women who were diagnosed as having benign breast disease and 150 age matched controls, with three controls per case. Matching was based on the age of the subject at the time of interview. Cases included women with a biopsy-confirmed diagnosis of fibrocystic breast disease identified through two hospitals in New Haven, Connecticut. Controls were selected from among patients admitted to the general surgery, orthopedic, or otolaryngologic services at the same two hospitals. Trained interviewers administered a standardized structured questionnaire to collect information from each subject [see Pastides et. al. (1983) and Pastides, et al. (1985)].
