Access to Data

The Schema is a timeline of the study. It indicates start/end points, visits expected, major testing to be done, and any other information that is crucial to understanding how the study was completed.



Schema Description

The study had participants split between the control and intervention arms. The intervention arm was scheduled for a clinical exam and mammography. If the participants attended the first exam they were scheduled for 3 subsequent annual exams. The control arm had no exams and women just received their usual medical care. There were mail surveys sent out 5, 10, and 15 years after trial entry. Death and cancer statistics were checked from a variety of sources including the National Death Index (after 1979), the New York Cancer Registry, HIP records, hospital claims files, and death records from several states.
