"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.
