Threshold effect analysis identified a critical turning point of -2.87 in TAT level changes (TATp2-1), below which the risk of adverse outcomes increased significantly (adjusted OR = 0.37, 95% CI: 0.22-0.63).</p><p><strong>Conclusion: </strong>The association between TATp2-1 and adverse pregnancy outcomes in early pregnancy VTE patients was non-linear. A threshold effect was observed with an inflection point of -2.87. When the TATp2-1 were below - 2.87, there was a significantly increased risk of adverse pregnancy outcomes.</p>","PeriodicalId":22982,"journal":{"name":"Thrombosis Journal","volume":"23 1","pages":"48"},"PeriodicalIF":2.6,"publicationDate":"2025-05-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12080146/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144080546","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
