Abstract
Background: In vitro and observational epidemiological studies suggest that vitamin D may play a role in cancer prevention. However, the relationship between vitamin D and ovarian cancer is uncertain, with observational studies generating conflicting findings. A potential limitation of observational studies is inadequate control of confounding. To overcome this problem, we used Mendelian randomization (MR) to evaluate the association between single nucleotide polymorphisms (SNPs) associated with circulating 25- hydroxyvitamin D [25(OH)D] concentration and risk of ovarian cancer. Methods: We employed SNPs with well-established associations with 25(OH)D concentration as instrumental variables ..
