The Breast Imaging Reporting and Database System (BI-RADS) is used to report mammographic findings. However, little is known about the clinical characteristics of Asian women with BI-RADS category 0, and we aimed to explore such characteristics in the context of Taiwan. This retrospective cross-sectional study was conducted using data from a single tertiary medical center. We examined the association of blood test data and estrogen exposure\u2013related medical histories with BI-RADS reports from screening mammography of 4280 women between 1 January 2010 and 31 July 2019. The data of 4280 participants were evaluated, and they were categorized into BI-RADS category 0 (n = 413; 9.6%) and 1\u20135 (n = 3867; 90.4%) subgroups. In a multivariate analysis, breast surgery history and premenopausal status had a positive relationship with a category 0 status, with respective risk increases of 64% and 34% (p = 0.010 and 0.013). Hormone contraceptive use for \u22655 years was a negative independent predictor of having a category 0 status. In conclusion, breast surgery history and premenopausal status significantly increased the likelihood of individuals having incomplete mammographic findings, even when they were older than 45 years. Identifying related factors before screening mammography is helpful for clinical physicians to arrange more proper and alternative examination and obtain a definite diagnosis.<\/jats:p>","DOI":"10.3390\/ijerph18105410","type":"journal-article","created":{"date-parts":[[2021,5,19]],"date-time":"2021-05-19T12:58:07Z","timestamp":1621429087000},"page":"5410","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Clinical Factors Associated with Asymptomatic Women Having Inconclusive Screening Mammography Results: Experiences from a Single Medical Center in Taiwan"],"prefix":"10.3390","volume":"18","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-6649-4478","authenticated-orcid":false,"given":"Chun-Li","family":"Wang","sequence":"first","affiliation":[{"name":"Institute of Medicine, Chung Shan Medical University, Taichung 40201, Taiwan"},{"name":"Department of Family Medicine, Taichung Veterans General Hospital, Taichung 40705, Taiwan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Pi-Shan","family":"Hsu","sequence":"additional","affiliation":[{"name":"Department of Family Medicine, Taichung Veterans General Hospital, Taichung 40705, Taiwan"},{"name":"Graduate Institute of Microbiology and Public Health, College of Veterinary Medicine, National Chung-Hsing University, Taichung 40227, Taiwan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6303-2187","authenticated-orcid":false,"given":"Chia-Yen","family":"Lin","sequence":"additional","affiliation":[{"name":"Institute of Medicine, Chung Shan Medical University, Taichung 40201, Taiwan"},{"name":"Division of Urology, Department of Surgery, Taichung Veterans General Hospital, Taichung 40705, Taiwan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0365-7927","authenticated-orcid":false,"given":"Shun-Fa","family":"Yang","sequence":"additional","affiliation":[{"name":"Institute of Medicine, Chung Shan Medical University, Taichung 40201, Taiwan"},{"name":"Department of Medical Research, Chung Shan Medical University Hospital, Taichung 40705, Taiwan"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2021,5,19]]},"reference":[{"key":"ref_1","unstructured":"Ministry of Health and Welfare (2020, September 14).
