## Cumulative incidence rate interpretation

Terminology 101: Cumulative incidence and incidence rate Incidence: The number of new cases of a disease that occur during a specified period of time in a population at risk for developing the disease. Cumulative incidence cannot be interpreted without specifying the time period. The cumulative incidence of death for the whole U.S. population at 1 year is about 0.8% but at 100 years it is greater than 99.9%. Incidence rate is a true rate whose denominator is the total of the groups individual times "at risk" (person-time). Cumulative Incidence. Cumulative incidence is the proportion of a population at risk that develops the outcome of interest over a specified time period. The relevant time period must be stated in words.

## Here are some definitions or explanations of specific terms and/or acronyms as they are An age-specific rate is the incidence or mortality rate for a specified age group, Cumulative incidence/mortality is the probability or risk of individuals

Incidence and prevalence are key concepts in epidemiology, the basic science of It could be defined as any research of health events in populations, including: or 14 cases per 1,000 person-years (incidence rate), because the incidence  For cumulative incidence, the denominator is the total number of "at risk" subjects being followed; for incidence rate, the denominator is the total amount of time "at risk" of continued pain for all the subjects who were being followed. Cumulative incidence, also called incidence proportion, in epidemiology, estimate of the risk that an individual will experience an event or develop a disease during a specified period of time. Cumulative incidence is calculated as the number of new events or cases of disease divided by the total number of individuals in the population at risk for a specific time interval. Terminology 101: Cumulative incidence and incidence rate Incidence: The number of new cases of a disease that occur during a specified period of time in a population at risk for developing the disease. Cumulative incidence cannot be interpreted without specifying the time period. The cumulative incidence of death for the whole U.S. population at 1 year is about 0.8% but at 100 years it is greater than 99.9%. Incidence rate is a true rate whose denominator is the total of the groups individual times "at risk" (person-time). Cumulative Incidence. Cumulative incidence is the proportion of a population at risk that develops the outcome of interest over a specified time period. The relevant time period must be stated in words. Cumulative Incidence is also known as the incidence proportion. In epidemiology, it is a measure of the frequency of disease during a period (entire lifetime). Use our cumulative incidence calculator to know the incidence proportion for a given number of an incident rate for a disease in a duration.

## The authors use the term “cumulative incidence rate,” when indeed cumulative incidence is a proportion, not a rate (events expressed per unit time) [2, 3]. For included studies that only contained information on cumulative incidence, but not an actual incidence rate, the authors used cumulative incidence (over the study period) divided by the incidence rate per year in the general population to calculate an incidence rate ratio.

So, incidence rate is a person-time measure, meaning the amount of time the study population was actually observed is measured (people who drop out early   Definition of Incidence Rate.
