Metal mixture analyses did not identify statistically significant associations with adolescent eGFR.</p><p><strong>Conclusions: </strong>These findings have important implications for future studies investigating the potential mechanisms through which prenatal metal exposures affect long-term kidney health in children.</p>","PeriodicalId":11686,"journal":{"name":"Environmental Health","volume":"23 1","pages":"94"},"PeriodicalIF":5.3,"publicationDate":"2024-10-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11526622/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142544452","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
