Multiple machine learning models, such as Logistic Regression, Random Forest, Gradient Boosting, and Voting Classifier, were developed. Metrics including Area Under the Curve(AUC), accuracy, precision, recall, F1 score, and specificity were used to evaluate model performance. Key predictors were identified through Mutual Information and Recursive Feature Elimination (RFE).<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Maternal age, paternal age, endometrial thickness, blastocyst quality, and ovarian stimulation parameters were identified as critical predictors. Compared to traditional statistical models such as logistic regression (AUC = 0.584), ensemble models demonstrated significantly improved predictive performance. The Voting Classifier achieved the highest AUC (0.836), accuracy (0.780), precision (0.914), and specificity (0.942), outperforming individual machine learning classifiers. The Gradient Boosting Classifier also exhibited strong performance (AUC 0.831, accuracy 0.777), confirming the effectiveness of ensemble learning in capturing complex predictors of early miscarriage risk.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>Ensemble machine learning models, particularly the Voting Classifier and Gradient Boosting Classifier, significantly improve the prediction of early miscarriage following SVBT. These models provide accurate, individualized risk assessments, enhancing clinical decision-making and advancing personalized care in ART.<\/jats:p><\/jats:sec>","DOI":"10.3389\/fendo.2025.1557667","type":"journal-article","created":{"date-parts":[[2025,4,16]],"date-time":"2025-04-16T04:10:37Z","timestamp":1744776637000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":9,"title":["Optimizing predictive features using machine learning for early miscarriage risk following single vitrified-warmed blastocyst transfer"],"prefix":"10.3389","volume":"16","author":[{"given":"Lidan","family":"Liu","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Bo","family":"Liu","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Huimei","family":"Wu","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Qiuying","family":"Gan","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Qianyi","family":"Huang","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mujun","family":"Li","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1965","published-online":{"date-parts":[[2025,4,16]]},"reference":[{"key":"B1","doi-asserted-by":"publisher","DOI":"10.1016\/S0140-6736(21)00682-6","article-title":"Miscarriage matters: the epidemiological, physical, psychological, and economic costs of early pregnancy loss","volume":"397","author":"Quenby","year":"2021","journal-title":"Lancet"},{"key":"B2","doi-asserted-by":"publisher","first-page":"575","DOI":"10.1186\/s12884-022-04904-8","article-title":"Incidence and risk factors for early pregnancy loss in women with first pregnancy undergoing in vitro fertilization-embryo transfer","volume":"22","author":"Wang","year":"2022","journal-title":"BMC Pregnancy Childbirth"},{"key":"B3","doi-asserted-by":"publisher","DOI":"10.14738\/assrj.710.9132","article-title":"Hypothyroidism in women with recurrent spontaneous abortion","volume":"7","author":"Emarah","year":"2020","journal-title":"Adv Soc Sci Res J"},{"key":"B4","doi-asserted-by":"publisher","DOI":"10.1016\/j.jri.2020.103166","article-title":"Two of a kind?
