Methods: A rule-based NLP algorithm that iteratively built a collection of regular expressions in testing data consisting of 889 snippets of text pulled from DXA reports. This was manually checked by clinical experts to determine the proportion of manually verified annotations that contained T-score information detected by this algorithm called \u2018BoneScore\u2019. Testing of 30- and 50-word lengths on each side of the key term \u2018femoral\u2019 were pursued until achievement of adequate accuracy. A separate clinical validation regressed the extracted T-score values on five risk factors with established associations. Results: BoneScore built a set of 20 regular expressions that in concert with a width of 50 words on each side of the key term yielded an accuracy of 98% in the testing data. The extracted T-scores, when modeled with multivariable linear regression, consistently exhibited associations supported by the literature. Conclusion: BoneScore uses regular expressions to accurately extract annotations of T-score values of bone mineral density with a width of 50 words on each side of the key term. The extracted T-scores exhibit clinical face validity.<\/jats:p>","DOI":"10.1177\/14604582241295930","type":"journal-article","created":{"date-parts":[[2024,11,11]],"date-time":"2024-11-11T08:49:52Z","timestamp":1731314992000},"update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":4,"title":["BoneScore: A natural language processing algorithm to extract bone mineral density data from DXA scans"],"prefix":"10.1177","volume":"30","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-4664-3143","authenticated-orcid":false,"given":"Samah","family":"Fodeh","sequence":"first","affiliation":[{"name":"Yale School of Medicine, New Haven, CT, USA"},{"name":"VA Connicticut Healthcare System, West Haven, CT, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Rixin","family":"Wang","sequence":"additional","affiliation":[{"name":"Yale School of Medicine, New Haven, CT, USA"},{"name":"VA Connecticut Healthcare System, West Haven, CT, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Terrence E","family":"Murphy","sequence":"additional","affiliation":[{"name":"Penn State College of Medicine, Hershey, PA, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Farah","family":"Kidwai-Khan","sequence":"additional","affiliation":[{"name":"Yale School of Medicine, New Haven, CT, USA"},{"name":"VA Connecticut Healthcare System, West Haven, CT, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Linda S","family":"Leo-Summers","sequence":"additional","affiliation":[{"name":"Yale School of Medicine, New Haven, CT, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Baylah","family":"Tessier-Sherman","sequence":"additional","affiliation":[{"name":"Yale School of Medicine, New Haven, CT, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Evelyn","family":"Hsieh","sequence":"additional","affiliation":[{"name":"Yale School of Medicine, New Haven, CT, USA"},{"name":"VA Connecticut Healthcare System, West Haven, CT, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Julie A","family":"Womack","sequence":"additional","affiliation":[{"name":"VA Connecticut Healthcare System, West Haven, CT, USA"},{"name":"Yale School of Nursing, New Haven, CT, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2024,11,11]]},"reference":[{"key":"bibr1-14604582241295930","doi-asserted-by":"publisher","DOI":"10.1097\/QAD.0000000000003128"},{"key":"bibr2-14604582241295930","doi-asserted-by":"publisher","DOI":"10.1111\/jgs.18304"},{"key":"bibr3-14604582241295930","doi-asserted-by":"publisher","DOI":"10.1097\/01.mlr.0000223670.00890.74"},{"key":"bibr4-14604582241295930","doi-asserted-by":"publisher","DOI":"10.11005\/jbm.2013.20.1.31"},{"key":"bibr5-14604582241295930","doi-asserted-by":"publisher","DOI":"10.1002\/jbmr.5650090602"},{"key":"bibr6-14604582241295930","doi-asserted-by":"publisher","DOI":"10.1016\/j.amepre.2008.03.027"},{"key":"bibr7-14604582241295930","doi-asserted-by":"publisher","DOI":"10.1016\/j.puhe.2004.10.018"},{"key":"bibr8-14604582241295930","doi-asserted-by":"publisher","DOI":"10.1016\/j.jocd.2010.03.003"},{"key":"bibr9-14604582241295930","first-page":"240","volume":"2014","author":"Allin S","year":"2014","journal-title":"AMIA Annu Symp Proc"},{"key":"bibr10-14604582241295930","doi-asserted-by":"publisher","DOI":"10.1016\/j.bone.2015.04.022"},{"key":"bibr11-14604582241295930","unstructured":"LaFleur J, Ginter T, Curtis JR, et al.
