Associations between 1400 metabolites and subtypes of endometriosis: a two-sample Mendelian randomisation study

Background Endometriosis is a chronic inflammatory disease with a prevalence of approximately 10% in women of childbearing age. Metabolic pathways have been demonstrated by previous studies to be potential avenues for the development of new therapeutic strategies and may be used for early diagnosis of the disease. This study aimed to investigate the potential causal relationships between 1400 metabolites and various endometriosis subtypes using Mendelian randomisation (MR) analysis.
