For alleles with incomplete penetrance, the penetrance of the allele is not the same as the attributable risk.

Projected relative risks attributable to climate change in 2030 varied by health outcome and region.

Although the risk of UV exposure is well known, quantifying its attributable risk to cancer development has proven challenging.

However the risk attributable to the hiatus hernia is difficult to quantify, and at most is low.

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

However, some epidemiologists use "attributable risk" when referring to the excess risk, also called the risk difference or rate difference.

The attributable risk is low, however, because they are so rare.

Each polymorphism may confer low relative and absolute risks, but collectively they may account for high attributable risk because they are so common.

It is defined as the inverse of the attributable risk.

The number needed to harm is the inverse of the attributable risk, or:
