# Incidence (epidemiology)

Incidence in epidemiology is a measure of the probability of occurrence of a given medical condition in a population within a specified period of time. [1]

## Attributable risk

In epidemiology, attributable risk or excess risk is the difference in rate of a condition between an exposed population and an unexposed population.

## Cumulative incidence

Cumulative incidence or incidence proportion is a measure of frequency, as in epidemiology, where it is a measure of disease frequency during a period of time.

## Denominator data

In epidemiology, data or facts about a population is called denominator data.

## Disease

A disease is any condition which results in the disorder of a structure or function in an organism that is not due to any external injury.

## Epidemiology

Epidemiology is the study and analysis of the distribution (who, when, and where) and determinants of health and disease conditions in defined populations.

## Kaplan–Meier estimator

The Kaplan–Meier estimator, also known as the product limit estimator, is a non-parametric statistic used to estimate the survival function from lifetime data.

## Man-hour

A man-hour, or less commonly person-hour, is the amount of work performed by the average worker in one hour.

## Oxford University Press

Oxford University Press (OUP) is the largest university press in the world, and the second oldest after Cambridge University Press.

## Prevalence

Prevalence in epidemiology is the proportion of a particular population found to be affected by a medical condition (typically a disease or a risk factor such as smoking or seat-belt use).

## Proportionality (mathematics)

In mathematics, two variables are proportional if there is always a constant ratio between them.
