Cervical Dysplasia Decision Analysis.

Here are the tables and figures for a decision analysis of the decision how to manage mild cervical dysplasia. This is a more complete and complex view of the tree than could be presented in the Journal of Family Practice 1998, Vol. 47, No. 3, pp 193-201,  in the paper by Robert M. Hamm, PhD, Vickie Loemker, MD, Kathryn L. Reilly, MD, MPH, Gary Johnson, MD, Peggy Dubois, MD, Kathleen Staveley-O'Carroll, MD, James Brand, MD, Tomas Owens, MD, and Kenneth Smith, MD entitled, "A Clinical Decision Analysis of Cryotherapy Compared to Expectant Management for Mild Cervical Dysplasia."
