The study period for included studies ranged from 1995 to 2016, most were from the USA. Four studies considering exposure to STIs and five to UTIs were eligible to progress to meta-analysis. Meta-analysis identified a significantly increased risk of gastroschisis in association with periconceptional exposure to UTI [OR 1.54 (95% CI 1.29, 1.8)], STI [OR 1.4 (95% CI 1.01, 1.79)].</p>\u0000 </section>\u0000 \u0000 <section>\u0000 \u0000 <h3> Conclusions</h3>\u0000 \u0000 <p>Periconceptional exposure to GUTI is associated with an increased risk of gastroschisis. The prevention and timely treatment of GUTI amongst women of childbearing age may help to reduce the occurrence of gastroschisis.</p>\u0000 </section>\u0000 </div>","PeriodicalId":9121,"journal":{"name":"Birth Defects Research","volume":"116 7","pages":""},"PeriodicalIF":1.6,"publicationDate":"2024-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/bdr2.2377","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141466178","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}
