Fig. 1From: A microbial causal mediation analytic tool for health disparity and applications in body mass indexMicrobiome (M) may play a mediating role in the health disparity of the continuous outcome (Y) between two categories of a non-manipulable exposure group (e.g., region or ethnicity) (R). We aim to investigate how much disparity of the outcome Y can be reduced by manipulating microbiome profilesBack to article page
