Daniel B. Kopans, Dean McKnight, Jack E. Meyer, Myron Moskowitz, Paul Stomper, and Clifford J. Turner. Drs. Moskowitz and Bartrum very kindly provided mammograms and associated case data from their studies at the University of Cincinnati and Dartmouth-Hitchcock Medical Centers. The authors are also indebted to Allison Hagerman for serving as reading-test administrator and technical assistant throughout the project; to Barbara Freeman for writing the computer programs required for data collection; and to A.
