description: <b>Summary</b><br> This metadata record provides details of the data supporting the claims of the related article: “Effectiveness of the Korean National Cancer Screening Program in Reducing Breast Cancer Mortality”. The related study aimed to determine whether mammographic screening reduces mortality among incidences of breast cancer in Asian women in their forties. Type of data: adjusted mortality rate ratio for breast cancer among screened and non-screened women estimated by Poisson regression Subject of data: <i>Homo sapiens</i> Population characteristics: Korean women aged 40-79 years, who were invited to the Korean National Cancer Screening Program (KNCSP) for breast cancer between 2002 and 2003 (N=8,300,682). Recruitment: Korean women aged 40 years and older are eligible for breast cancer screening services through the Korean National Cancer Screening Program (KNCSP) and automatically enrolled in the screening database. Screening records and results are accumulated from those who underwent breast cancer screening. Regardless of screening attendance, the eligible women in the screening database are followed through 2015 by linkage to cancer registry data and death certificates. <b>Data access</b> The data are contained in the following SAS data files: an_list_br_2002.sas7bdat, an_list_br_2003.sas7bdat, an_result_br_2002.sas7bdat, an_result_br_2003.sas7bdat, an_result_br_2004.sas7bdat, an_result_br_2005.sas7bdat, an_result_br_2006.sas7bdat, an_result_br_2007.sas7bdat, an_result_br_2008.sas7bdat, an_result_br_2009.sas7bdat, an_result_br_2010.sas7bdat, an_result_br_2011.sas7bdat, an_result_br_2012.sas7bdat, an_result_br_2013.sas7bdat, an_result_br_2014.sas7bdat, cancer_total.sas7bdat, samang.sas7bdat.
