However, according to the IVW results, genetically predicted kidney and ureteral stones were associated with decreased serum 25(OH)D levels (beta = -0.025; 95% CI, -0.048 to -0.003; p = 0.028), while they did not indicate a causal effect of lower urinary tract stones on serum 25(OH)D levels (beta = -0.002; 95% CI, -0.013 to -0.008; p = 0.662). A sensitivity analysis suggested the robustness of these causal associations.</p><p><strong>Conclusions: </strong>Our MR study did not provide evidence supporting a causal association between serum 25(OH)D levels and urolithiasis among individuals of European descent. However, there might exist a negative causal association between kidney and ureteral stones and serum 25(OH)D levels.</p>","PeriodicalId":12030,"journal":{"name":"European Journal of Nutrition","volume":"64 1","pages":"39"},"PeriodicalIF":4.1,"publicationDate":"2024-11-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142767472","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
