How are chi squared and CI related?

The chi-square test and the CI are closely related. The chi-square test uses the observed data to determine the probability ( p value) under the null hypothesis, and one rejects the null hypothesis if the probability is less than alpha (e.g., 0.05). The CI uses a preselected probability value, alpha (e.g., 0.05), to determine the limits of the interval (1 − alpha = 0.95), and one rejects the null hypothesis if the interval does not include the null association value. Both indicate the precision of the observed association; both are influenced by the magnitude of the association and the size of the study group. Although both measure precision, neither addresses validity (lack of bias).

What is a two by two table?

A two-by-two table is so named because it is a cross-tabulation of two variables—exposure and health outcome—that each have two categories, usually “yes” and “no” ( Handout 8.3 ). The two-by-two table is the best way to summarize data that reflect the association between a particular exposure (e.g., consumption of a specific food) and the health outcome of interest (e.g., gastroenteritis). The association is usually quantified by calculating a measure of association (e.g., a risk ratio [RR] or OR) from the data in the two-by-two table (see the following section).

How to control for confounding?

One method of controlling for confounding is by calculating a summary RR or OR based on a weighted average of the stratum-specific data. The Mantel-Haenszel technique ( 6) is a popular method for performing this task.

The OR is the preferred measure of association for case–control data. Conceptually, it is calculated as the odds of exposure among case-patients divided by the odds of exposure among controls. However, in practice, it is calculated as the cross-product ratio. Using the notations in Handout 8.3,
