Causal link between folic acid and recurrent aphthous ulcers: A two-sample Mendelian randomization study.

Abstract excerpt

Observational studies have suggested associations between micronutrient status and recurrent aphthous ulcers (RAU); however, the causal nature of these relationships remains unclear. This study aimed to evaluate the genetically predicted associations between circulating micronutrients and RAU using a Mendelian randomization (MR) approach. We conducted a two-sample MR analysis using genome-wide association study...
