A crude incidence rate is the number of new cancers of a specific site/type occurring in a specified population during a year, usually expressed as the number of cancers per 100,000 population at risk. It is calculated using the following formula: Age. Count. Population. Crude Rate.

WebDefinition of risk ratio. A risk ratio (RR), also called relative risk, compares the risk of a health event (disease, injury, risk factor, or death) among one group with the risk among another group. It does so by dividing the risk (incidence proportion, attack rate) in group 1 by the risk (incidence proportion, attack rate) in group 2. WebJul 1, 2000 · Prevalence = Incidence X Duration So, for a given incidence rate, the prevalence will be higher if the duration of the disease is longer - as an example, the prevalence of arthritis in an elderly population is high since there is no cure for the condition so once diagnosed the person has it for the rest of their lives. chrysler 300 long tube headersWebIn contrast, a disease that has a short duration may have a low prevalence and a high incidence.
