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 or incidence proportion is a measure of frequency, as in epidemiology, where it is a measure of disease frequency during a period of time.
In epidemiology, data or facts about a population is called denominator data.
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 is the study and analysis of the distribution (who, when, and where) and determinants of health and disease conditions in defined populations.
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.
A man-hour, or less commonly person-hour, is the amount of work performed by the average worker in one hour.
Oxford University Press (OUP) is the largest university press in the world, and the second oldest after Cambridge University Press.
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).
In mathematics, two variables are proportional if there is always a constant ratio between them.
