RESEARCH AND DESIGN IN EPIDEMIOLOGY AND PUBLIC HEALTH The concept of the agent has been broadened to include chemical and physical causes of disease or injury, such as chemical contaminants. For example, contamination of poor-quality nutritional supplements containing L-tryptophan was deemed responsible for occurrences of eosinophilia–myalgia syndrome, an incurable and sometimes fatal flulike neurological condition. (Tryptophan is an essential amino acid in the human diet. ) Although the epidemiologic triangle (or triad) serves as a useful model for many diseases, it has proven inadequate for cardiovascular disease, cancer, and other diseases that appear to have multiple contributing causes without a single necessary one.

Temporal relationship. Exposure always precedes the outcome. If factor A is believed to cause a disease, then that factor A must necessarily always precede the occurrence of the disease. This is the only absolutely essential criterion. 1 Causation and Association in Epidemiology and Public Health 27 2. Strength of association. This criterion is defined by the size of the association as measured by appropriate biostatistical tests. The stronger the association, the more likely it is that the relation of A to B is causal.

A binomial model of distribution of the disease 2. 008, from which biostatistical predictions may be made using the well-known binomial distribution model. ) Thus, for a large population (under the same condition of distribution) of n = 1,000,000, one would use the same model (assumed to be reasonably applicable) to get the expected number of disease cases. 008) = 8,000. Clearly, major assumptions have been made. For example, it was assumed that (a) the binomial distribution model was applicable; and (b) only one sampling population was used.
