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

emanating from or pertaining to attribute.

attributable proportion
see attributable risk (below).
attributable risk
a measure of the proportion of the total risk which can be attributed to the risk factor which is under consideration. Called also attributable proportion.

10) Formula 1a (8) PAF = Attributable risk * Risk factor exposure prevalence/Total asthma prevalence = [a/(a + b)-c/(c + d)] * (a + b)/(a + b + c + d)/ (a + c)/(a + b + c + d) = [a/(a + b)--c/(c + d)] * (a + b)/(a + c) Formula 1b (9) PAF = (Relative risk-1/Relative risk) * Proportion of cases exposed to risk factor = {[a/(a + b)]/[c/(c + d)] - 1}/[a/(a + b)]/[c/(c + d)] * a/(a + c) = {[a/(a + b)]/[c/(c + d)] - [c/(c + d)]/[c/(c + d)]}/[a/(a + b)]/ c/(c + d)] * a/(a + c) = [a/(a + b) - c/(c + d)]/[a/(a + b)] * a/(a + c) = [a/(a + b) - c/(c + d)] * (a + b)/(a + c) Therefore, formulae 1a and 1b are algebraically equivalent.
