Related to relative risk: absolute risk, Attributable 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.

rel·a·tive risk (RR),

the ratio of the risk of disease among those exposed to a risk factor to the risk among those not exposed.

relative risk

the ratio of the chance of a disease developing among members of a population exposed to a factor compared with a similar population not exposed to the factor. In many cases the relative risk is modified by the duration or intensity of exposure to the causative factors.

rel·a·tive risk

(RR) (relă-tiv risk)
Ratio of the risk of disease among those exposed to a risk factor to the risk among those not exposed.


relates to the condition of one animal when it is considered in connection with another.

relative biological effectiveness (RBE)
see rbe.
relative frequency
the proportion of the total number of observations of a variable which are observations of a particular value.
relative odds
see odds ratio.
relative population index
a measure of a population based on a sampling technique such as line transects which determine the number of animals in a given ecological niche relative to a period of examination, or other parameter.
relative risk
the ratio of the disease incidence rate in animals exposed to an hypothesized cause to the incidence rate in animals not exposed. A measure of association commonly used in epidemiological studies. Called also risk ratio.


the chance of an unfavorable event occurring.

acceptable risk
risk for which the benefits rank larger than the potential hazards.
at risk
that part of a total population which is subject to the disease being reviewed, e.g. only milking cows are at risk to milk fever, only grazing cows to enzootic nasal granuloma.
risk aversion
reluctance to take risks.
risk factor
