However, translating such a model into field application requires a stepwise approach. This article describes a decision tree developed to assist public health workers in determining which contacts are most likely to have a positive tuberculin skin test. The Classification and Regression Tree analysis was performed on 292 consecutive cases and their 2,941 contacts seen by the Alabama Department of Public Health from January 1, 1998, to October 15, 1998. Several decision trees were developed and were then tested using prospectively collected data from 366 new tuberculosis cases and their 3,162 contacts from October 15, 1998, to April 30, 2000. Testing showed the trees to have sensitivities of 87\u201394%, specificities of 22\u201328%, and false-negative rates between 7 and 10%. The use of the decision trees would decrease the number of contacts investigated by 17\u201325% while maintaining a false-negative rate that was close to that of the presumed background rate of latent tuberculosis infection in the state of Alabama.<\/jats:p>","DOI":"10.1164\/rccm.200202-124oc","type":"journal-article","created":{"date-parts":[[2002,10,14]],"date-time":"2002-10-14T22:34:59Z","timestamp":1034634899000},"page":"1122-1127","source":"Crossref","is-referenced-by-count":54,"title":["A
