Health disparity analyses in two matched datasets from the curatedMetagenomicData package [28]. a The average and standard error of manipulable disparity measure (MDM) and residual disparity measure (RDM) of BMI in the China-USA comparison and China-UK comparison, respectively, based on the splitting strategy with 50 times of repetitions. b Component-wise point and 95% CI estimates of \({MDM}_{j}\) for the identified species that have mediation effects on the differences of BMI between matched Chinese vs. USA subjects and between matched Chinese vs. UK subjects, respectively. 95% CI estimates of \({MDM}_{j}\) were calculated based on the splitting strategy with 50 times of repetitions. c Venn diagram to show the relationship of the species playing mediation effects in the disparity of BMI among China-USA, China-UK, and API-Caucasian comparisons.
