What incidence rate and prevalence rate?
prevalencerefers to the number of cases of disease thatexistsin a population and the incidence refers to the number of new cases of diseaseoccurringin a population.
What is the formula of incidence rate?
# of new cases of a specified disease in a population / population at risk for getting the disease
How do you calculate relative risk from incidence rate?
Relative risk (RR) can be calculated by comparing the incidence rates of an event occurring in two groups. First, determine the incidence rate in the exposed group (e.g., those with a risk factor) and the incidence rate in the unexposed group (e.g., those without the risk factor). Then, divide the incidence rate of the exposed group by the incidence rate of the unexposed group (RR = Incidence Rate in Exposed / Incidence Rate in Unexposed). A RR greater than 1 indicates increased risk, while a RR less than 1 indicates decreased risk.
How do you calculate absolute risk?
=incidence

What is the rate of incidence?

What race has the highest incidence rate of coronary heart disease?

What is incidence of disease?
The rate at which a disease occurs. IE; one in five people, one in twenty people, etc.
How do you calculate relative risk from incidence rate?
Relative risk (RR) can be calculated by comparing the incidence rates of an event occurring in two groups. First, determine the incidence rate in the exposed group (e.g., those with a risk factor) and the incidence rate in the unexposed group (e.g., those without the risk factor).

A RR greater than 1 indicates increased risk, while a RR less than 1 indicates decreased risk.
In epidemiology there are 2 measures incidence rate and the prevalence rate How do these differ?
Incidence rate measures the number of new cases of a disease that occur in a specific population during a defined time period, reflecting the risk of developing the disease. In contrast, prevalence rate indicates the total number of existing cases (both new and pre-existing) of a disease in a population at a particular point in time, providing insight into the overall burden of the disease. While incidence focuses on new occurrences, prevalence encompasses all cases, highlighting the disease's impact on a population.
What is an age standardized rate?
An age standardized rate is, in the field of medicine, the incidence rate of a particular disease in a population assuming the population has a standard age structure.
What is the difference between incidence rate ratio and relative risk ratio?
Incidence rate and relative risk are two different measurements used in epidemiology to study illness/disease in specified populations.Incidence rate refers to the number of new cases of a condition in a defined (specified) group or population. It is often expressed as a ratio. For example, if there are 1000 people and 14 of them develop a condition, the incidence rate is 14 per 1000 or 1.4%Relative risk is a measurement that indicates probability of cause. In other words, how likely is it that a place, person or agent is responsible for causing disease/illness.Before you can calculate relative risk, you must first calculate an attack rate on different groups. An attack rate refers to the number of people exposed to an illness compaired to those who actually became sick. To calculate the attack rate, you divide the number of people ill by those who were exposed, and then multiply by 100.To then calculate the relative risk, you divide the attack rate of those sick by the attack rate of those who are not sick.The closer the relative risk is to 1.0, the less likely it is the cause of disease.The higher the relative risk, the more likely it is that it is the cause of disease.
What is the formula to calculate cumulative incidence rate?
CI(t)=1-e-IR(t)*D
