Similarly VanderWeeles definition will sometimes describe effect modification. Or changes only the magnitude of effect. Whereas effect modifiers are those that also cause an apparent association between the exposure and outcome when one does exists but this is by virtue of the effect modifiers association with the outcome. On the definition of effect modification. Effect modification means that the association between a predictor and outcome may be different depending on a third variable. In quantitative effect modification the modifier may strengthen or weaken the effect of the primary exposure but the direction of effect does not change.

Effect modification is all about stratification and occurs when an exposure has a different effect among different subgroups. Effect Measure Modification The term effect modification is applied to situations in which the magnitude of the effect of an exposure of interest differs depending on the level of a third variable. A systematic error in the design recruitment data collection or analysis that results in a mistaken estimation of the true effect of the exposure and the outcome. Effect modification happens when a particular variable has separate different exposure effects depending on another variable. In this situation computing an overall estimate of association is misleading.
