Quick Reference

The relationship of observed outcomes in a patient or population to the quantity of medication or level of exposure to an environmental health determinant. For instance, a linear dose-response relationship reflects a direct increase in risk as exposure increases. The dose-response relationship has central importance in toxicology and environmental health. The cumulative dose, as well as the size of an individual dose, may be important, for instance, in exposure to trace amounts of carcinogens, such as those in tobacco.
