Summary of Interaction
More often than not, disease is not predicated on the presence of only a single causal factor. Rather, multiple factors interacting together lead to the pathogenesis of disease. When the effect of multiple factors added together is greater than expected, it is referred to as synergism. When the effect of multiple factors is less than expected, it is referred to as antagonism.
Flashcards on Interaction
Interaction between exposures can occur when there is a (confounding/causal) relationship between exposure and disease.
