No Association Between Vitamin D Status and Risk of Barrett's Esophagus or Esophageal Adenocarcinoma—a Mendelian Randomization Study

Epidemiology studies of circulating concentrations of 25 hydroxy vitamin D (25(OH)D) and risk of esophageal adenocarcinoma (EAC) have produced conflicting results. We conducted a Mendelian randomization study to determine the associations between circulating concentrations of 25(OH)D and risks of EAC and its precursor, Barrett's esophagus (BE).
