Consistency The association is repeatedly observed in studies performed by different people, in different settings, among different populations and using different methods. Specificity A specific exposure can be isolated from others and associated with a specific disease. This is often the most difficult criteria to fulfill, because many exposures are associated with multiple effects and specific diseases often have more than one cause. Temporality The exposure/occurrence identified to have caused the disease must have occurred prior to the disease development. Biologic Gradient A dose- response is present, so that as the exposure increases, either the risk of the disease onset or the severity of disease also
