* Mortality reductions are absolute reductions, computed as the difference between the rate predicted in the absence of both screening and adjuvant treatment and the rate predicted with one or both interventions. Chemo = chemotherapy; ER = estrogen receptor; SCR = screening mammography; SCR+TX = screening mammography and tamoxifen and chemotherapy; Tam = tamoxifen; TX = tamoxifen and chemotherapy.
