ARTICLES Quantitative Interpretation of Age-Specific Mortality Reductions From the Swedish Breast Cancer-Screening Trials die to J. de Koning, Rob Boer, Peter G. Warmerdam, Petra M. M. Beemsterboer, Paul J. van der Maas* served mortality lessening among the trials are estimated to be relatively small. (Expected mortality diminutions range from 24% to 32%.) Conclusions: Results from the Swedish randomized breast crab louse- binding trials should be seen as more favorable regarding the effect of mammographic screening in diminution breast cancer mortality for women senior(a) 50-69 years than was estimated earlier. Our analyses too suggest that the improvement in prognosis due to screening for women erad 40-49 years is much smaller than that for women aged 50 years or older. Approximately, 70% of the 10% observed reduction in breast cancer mortality (i.e., 7%) for women aged 40-49 years at trial entry might be attributable to a reduction due to screening these women after(prenominal) they reach age 50. Implications: Detailed screening data for the 40- to 49-year age group of all Swedish trials should be analyzed to specifically estimate the natural history and performance of screening in this age group.

[J Natl Cancer Inst 87:1217-1223,1995] Background: Results from 5 Swedish randomized trials may provide the around determinate evidence on the effect of mammographic screening and have been apply to forecast the expected reduction in breast cancer mortality in other programs. However, those trials demonstrated different degrees of reduction. The variation of observed mortality reduction after long review article for women aged 40-49 years at trial entry is both important and controversial. Purpose: We estimated what percentage of the observed mortality reduction for women aged 40-49 years at entry into the five Swedish screening trials might be attributable to screening these women at 50 years of age or older. Moreover, we calculated the most likely percentage mortality reduction for... If you want to get a full essay, order it on our website: Ordercustompaper.com
