Related to attributable risk: Relative risk

risk

 [risk]
a danger or hazard; the probability of suffering harm.
attributable risk the amount or proportion of incidence of disease or death (or risk of disease or death) in individuals exposed to a specific risk factor that can be attributed to exposure to that factor; the difference in the risk for unexposed versus exposed individuals.
empiric risk the probability that a trait will occur or recur in a family based solely on experience rather than on knowledge of the causative mechanism. See also genetic risk.
genetic risk the probability that a trait will occur or recur in a family, based on knowledge of its genetic pattern of transmission. See also empiric risk.
relative risk for a disease, death, or other outcome, the ratio of the incidence rate among individuals with a given risk factor to the incidence rate among those without it.

at·tri·but·a·ble risk

the rate of a disease or other outcome in exposed individuals that can be attributed to the exposure.

attributable risk

Epidemiology Any factor which ↑ the risk of suffering a particular condition. See Relative risk, Risk factor. Cf Nonattributable risk Statistics The rate of a disorder in exposed subjects that is attributable to the exposure derived from subtracting the rate–incidence or mortality of the disorder of a nonexposed population from the rate in an exposed population.

Attributable risk was defined as the incidence proportion in the exposed group minus the incidence proportion in the UNX group, which was adjusted for differences in the distribution of covariates between groups.
