WebResults: We introduced a sparse compositional mediation model for binary outcomes to estimate and test the mediation effects of the microbiome utilizing the compositional algebra defined in the simplex space and a linear zero-sum constraint on probit regression coefficients. For this model with the standard causal assumptions, we showed that ... WebMediation analysis is an important statistical method in prevention research, as it can be used to determine effective intervention components. Traditional mediation analysis defines direct and indirect effects in terms of linear regression coefficients. It is unclear how these traditional effects are estimated in settings with binary variables.

WebMar 4, 2024 · The difference method is used in mediation analysis to quantify the extent to which a mediator explains the mechanisms underlying the pathway between an exposure and an outcome. In many health science studies, the exposures are almost never measured without error, which can result in biased effect estimates. WebMediation is the process through which an exposure causes disease. In the simple diagram below we examine the total effect of exposure on outcome. Researchers may hypothesize that some or all of the total effect of exposure on an outcome operates through a mediator, which is an effect of the exposure and a cause of the outcome.
