These outcomes are corroborated by subsequent analyses for pleiotropy, heterogeneity, and sensitivity. On the other hand, reverse Mendelian randomization indicates that VD does not causally influence the levels of the 35 examined serum and urine biomarkers.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>The outcomes of this Mendelian randomization study affirm the causal influence of biomarkers AST, TG, and DBil on the progression of VD.
