A=Annual
B=Biennial
Average number of mammograms across models. Not all possible mammograms in the age interval are obtained in strategies that continue to the oldest age groups since many women die as the result of other causes before screening would occur.
Model Group Abbreviations: D (Dana Farber Cancer Center), E (Erasmus Medical Center), G (Georgetown U.), M (M.D. Anderson Cancer Center), S (Stanford U.), W (U. of Wisconsin/Harvard)
Shaded areas in the table show strategies that are dominated within a specific model; a strategy is classified as dominated if there is another strategy (from either the Efficient, Borderline or Dominated categories) that results in an equal or higher years of life gained with fewer average screening exams.
