Analysis of dietary vitamin C intake levels and the risk of hyperuricemia and gout based on cross-sectional studies and bi-directional Mendelian randomisation

Abstract

Background Vitamin C, a common antioxidant, may be useful for treating hyperuricemia and gout. The aim of this study was to investigate the risk association between dietary vitamin C intake and hyperuricemia/gout and to test for causality using the bi-directional Mendelian randomisation method.
