Association between antioxidants and pelvic inflammatory disease: a nationwide survey and mendelian randomisation study

A higher dietary antioxidant intake, as measured by the CDAI, is associated with a lower prevalence of PID in US women. However, our MR findings do not support a causal role for individual antioxidants in the development of PID. Further longitudinal studies are warranted to enhance our understanding of the interactions between antioxidants and PID.
