Question

How do you calculate relative risk and odds ratio?

Answer 1

To calculate the relative risk and odds ratio, you need to organize the data in a 2x2 table and calculate the incidence of the health event in the exposed and non-exposed groups. Then divide the incidence in the exposed group by the incidence in the non-exposed group.

Step-by-step explanation:

In epidemiology, the relative risk (RR) and odds ratio (OR) are used to measure the association between a risk factor and a health outcome. To calculate the relative risk, you divide the incidence of the health event in the exposed group by the incidence in the non-exposed group. For odds ratio, you divide the odds of the health event occurring in the exposed group by the odds in the non-exposed group.

For example, to calculate relative risk:

1. Organize the data in a 2x2 table.
2. Calculate the incidence of the health event in the exposed and non-exposed groups.
3. Divide the incidence in the exposed group by the incidence in the non-exposed group.
