The risk or rate difference estimates the excess risk caused by exposure in the exposed group, that is, the risk ...

We search for the determinants of health outcomes, first, by relying on descriptive epidemiology to generate hypotheses about associations between exposures and outcomes, and, second, by employing analytical epidemiology to more rigorously assess hypotheses by drawing samples of people and comparing … See more After successfully completing this section, the student will be able to: 1. Construct a tables for summarizing epidemiologic data. 2. Explain how to compare the … See more In a previous module we saw that we can measure disease frequency (cumulative incidence, incidence rate, or prevalence) by identifying the number of cases in the … See more Measures of disease frequency can be compared by calculating their ratio. Common terms to describe these ratios are 1. risk ratio 2. rate ratio 3. relative risk 4. … See more Rate ratios are closely related to risk ratios, but they are computed as the ratio of the incidence rate in an exposed group divided by the incidence rate in an … See more Webentire population or a random representative sample of the population since those are the types ...

It is the ratio of people who have a medical event compared to all of the people who could have an event.

The higher the denominator (the bottom number), the lower the absolute risk. culinary physics
