2. Methods 2.1 Study Design and Data Sources This study employed a two-sample Mendelian randomization approach to investigate the potential causal relationship between fitness-related metabolites and the risk of MG and LOMG. We utilized summary data from large-scale genome-wide association studies (GWAS) to obtain instrumental variables for the exposure (fitness supplement-related metabolites) and outcomes (MG, LOMG).
