The cohort was predominantly male, with a mean baseline CD4 cell count of 384 cells\/\u03bcL. Four machine learning models\u2014Support Vector Machine, Random Forest, Logistic Regression and Extreme Gradient Boosting (XGBoost)\u2014were developed. The XGBoost model demonstrated the best predictive performance (area under the curve, AUC: 0.877). Univariate and multivariate analyses identified WHO clinical stages, CD4 cell count, HIV transmission route, platelet count and haemoglobin level as significant predictors. The developed nomogram achieved an AUC of 0.840. Its calibration curve, after bias correction, showed good agreement with the ideal curve, and decision curve analysis indicated potential clinical utility.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>In this cohort, the XGBoost model showed superior performance for predicting AIDS progression. The proposed nomogram may serve as a practical tool to facilitate rapid risk assessment in similar clinical settings. These findings suggest that enhanced monitoring and regular follow-up might be beneficial for patients with low CD4 counts for timely intervention and to improve outcomes.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1136\/bmjopen-2025-105026","type":"journal-article","created":{"date-parts":[[2025,11,4]],"date-time":"2025-11-04T13:47:06Z","timestamp":1762264026000},"page":"e105026","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":1,"title":["Predicting disease progression in people living with HIV using machine learning and a nomogram: a 10-year cohort study based in Xinjiang, China"],"prefix":"10.1136","volume":"15","author":[{"given":"Qianru","family":"Mao","sequence":"first","affiliation":[{"name":"Xinjiang Medical University, Urumqi, Xinjiang, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Qian","family":"He","sequence":"additional","affiliation":[{"name":"Xinjiang Medical University, Urumqi, Xinjiang, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yongkang","family":"Ni","sequence":"additional","affiliation":[{"name":"Xinjiang Medical University, Urumqi, Xinjiang, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zhen","family":"Ni","sequence":"additional","affiliation":[{"name":"Xinjiang Uygur Autonomous Region Centre for Disease Control and Prevention, Urumqi, Xinjiang, China"},{"name":"Xinjiang Uygur Autonomous Region Academy of Preventive Medicine, Urumqi, Xinjiang, China"},{"name":"Xinjiang Key Laboratory for AIDS Prevention and Control Research, Urumqi, Xinjiang, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Changyu","family":"Zeng","sequence":"additional","affiliation":[{"name":"Xinjiang Uygur Autonomous Region Centre for Disease Control and Prevention, Urumqi, Xinjiang, China"},{"name":"Xinjiang Uygur Autonomous Region Academy of Preventive Medicine, Urumqi, Xinjiang, China"},{"name":"Xinjiang Key Laboratory for AIDS Prevention and Control Research, Urumqi, Xinjiang, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jiliang","family":"Wang","sequence":"additional","affiliation":[{"name":"Xinjiang Uygur Autonomous Region Centre for Disease Control and Prevention, Urumqi, Xinjiang, China"},{"name":"Xinjiang Uygur Autonomous Region Academy of Preventive Medicine, Urumqi, Xinjiang, China"},{"name":"Xinjiang Key Laboratory for AIDS Prevention and Control Research, Urumqi, Xinjiang, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xiaoyan","family":"He","sequence":"additional","affiliation":[{"name":"Yining Second People\u2019s Hospital, Yining, Xinjiang, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xinhuan","family":"Feng","sequence":"additional","affiliation":[{"name":"Yining People\u2019s Hospital, Yining, Xinjiang, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0006-0275-7914","authenticated-orcid":false,"given":"Mingjian","family":"Ni","sequence":"additional","affiliation":[{"name":"Xinjiang Uygur Autonomous Region Centre for Disease Control and Prevention, Urumqi, Xinjiang, China"},{"name":"Xinjiang Uygur Autonomous Region Academy of Preventive Medicine, Urumqi, Xinjiang, China"},{"name":"Xinjiang Key Laboratory for AIDS Prevention and Control Research, Urumqi, Xinjiang, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"239","published-online":{"date-parts":[[2025,11,4]]},"reference":[{"key":"2025120413254118000_15.11.e105026.1","unstructured":"UNAIDS .
