Effect * – Concerning a cause, the change produced by its being present (in lieu of its alternative) – in epidemiology, mainly, the increase in the level of morbidity from an illness.

Note: The I.E.A. dictionary says, under ‘Effect,’ this: “The result of a cause. In epidemiology, frequently a synonym for effect measure.” But where the concept of effect is equated with any measure of it, the researchers are using the word ‘effect’ in the loose meaning that prevails in statistics. (In clinical medicine, the concept of, say, glucose intolerance is not equated with any particular measure of it.) (See ‘Effect measure.’)
