It is used to determine the effect of one variable on Descriptive studies Identify disease problem in community Relate to environment & host factor Suggest an etiological hypothesis Analytical & experimental studies Test the hypothesis derived for observed RELATIONSHIP b/w suspected cause & disease. Two hundred years after Adam Smith, some economists still have not learned to apply basic principles of human nature. When researchers find a correlation, which can also be called an association, what they are saying is that they found a relationship between two, or more, variables. Association and Causation Association is a connection between two social phenomena, demonstrated by onetendingto vary according to variations in the other, whereas causality is a special case of association, when changes in one systematically result in direct changes in the other. Association should not be confused with causality; if X causes Y, then the two are associated (dependent). Causation 1c: Association vs causation. Enjoy!

Concept of disease causation (1) Srividhya Ramaswamy. Recap of Causation 1a and Causation 1b: We would like to make causal statements of how exposures (or treatments) cause outcomes. 2. Confounding occurs when an exposure and an outcome share a common cause (the confounder; Figure 1). Every case of the disease must have the agent present. Inferring causation from a single association study may therefore be misleading, and could potentially cause harm to the public. To do so, we need to know what outcome occurs when a person is exposed to something, vs what outcome occurs when the person is NOT exposed to the same thing. In research, there is a common phrase that most of us have come across; correlation does not mean causation.. Kochs postulates- The germ theory of disease insisted that the cause must be a. necessary and b. sufficient for the occurrence of the disease. 11. It is difficult, therefore, to understand the conclusion by Dr Vodopick in her clinical report entitled "Cherchez la Chienne" (234:850, 1975).Despite her statement that "exposure to a chemical Failure to control for the confounder makes it appear that there is Correlation means there is a statistical association between variables.

This is a major reason why preliminary results Association does not mean causation. The reason why this is so important is that studies that have only found associations make up the vast bulk of scare stories in the media: Here is a typical recent headline, which you may have seen: Eating red meat regularly dramatically increases the risk of death from heart disease.
