The model's graphic structure was based on the published literature. Results from 375\u200a441 patient records from 2005 through 2008 were used to build and train the model. Additional data from 45\u200a930 patients were used to test the model.<\/jats:p>\n                  <jats:p>Results.\u2014The PCCSM compares risk quantitatively over time for histopathologically verifiable CIN2, CIN3, adenocarcinoma in situ, and cervical cancer in screened patients for each current cytology result category and for each HPV result. For each current cytology result, HPV test results affect risk; however, the degree of cytologic abnormality remains the largest positive predictor of risk. Prior history also alters the CIN2, CIN3, adenocarcinoma in situ, and cervical cancer risk for patients with common current cytology and HPV test results. The PCCSM can also generate negative risk projections, estimating the likelihood of the absence of histopathologic CIN2, CIN3, adenocarcinoma in situ, and cervical cancer in screened patients.<\/jats:p>\n                  <jats:p>Conclusions.\u2014The PCCSM is a dynamic Bayesian network that computes quantitative cervical disease risk estimates for patients undergoing cervical screening. Continuously updatable with current system data, the PCCSM provides a new tool to monitor cervical disease risk in the evolving postvaccination era.<\/jats:p>","DOI":"10.5858\/134.5.744","type":"journal-article","created":{"date-parts":[[2021,2,12]],"date-time":"2021-02-12T12:24:07Z","timestamp":1613132647000},"page":"744-750","source":"Crossref","is-referenced-by-count":33,"title":["The Pittsburgh Cervical Cancer Screening Model: A Risk Assessment Tool"],"prefix":"10.5858","volume":"134","author":[{"given":"R.
