con·cor·dance rate

the proportion of a random sample of pairs that are concordant for a trait of interest. A high rate of concordance may be generated in several ways, many of which may result from irrelevant bias; but broadly it is taken as evidence of causal connection (for example, in the case of identical twins, a genetic component or in spouses of assortative mating).

concordance rate

n.
A quantitative statistical expression for the concordance of a given trait, especially in pairs of twins in genetic studies.

con·cor·dance rate

(kŏn-kōr'dăns rāt)
The rate of occurrence of a trait, behavior, or action in members of a specified group as compared with the occurrence of a trait of interest. Broadly, it is taken as evidence of causal connection.

concordance rate

The frequency with which a gene will be inherited or expressed by identical or fraternal twins.

The concordance rate for identical twins (52 percent) was much higher than the concordance rate for the fraternal twins (22 percent).
Perhaps those with fewer planned visits have a higher concordance rate because of the possibility that the task of the intake care manager is simplified for those needing fewer services, and the concordance rate for those with a larger number of initial planned visits might be lower, because the task of the intake care manager is more difficult.
The low concordance rate among monozygotic and dizygotic twins, as well as the similar prevalence in twins and in the general population, "supports the hypothesis that nonhereditary factors are important in the cause of Parkinson's disease," the researchers concluded.
The degree of concordance was assessed by calculating, for each needle group, a kappa statistic, overall concordance rate and the risk to undergrade a biopsy GS=6.
For each tumor sample, the per-specimen concordance rate was calculated as the proportion of raters who provided a classification that was the same as that of the reference evaluation.
Among the female dizygotic twins of 76 boys with ASD, the probandwise concordance rate was 5.
The concordance rate was calculated by dividing the number of matched SNPs by the number of SNPs compared.
The [kappa] statistic is very sensitive to marginal values; if the marginal values are not well balanced, the value will be low even if the concordance rate is high [28].
The primary endpoint for both the NEO3-05 and NEO3-09 trials was the comparison (the Concordance Rate, or the rate of agreement) of Lymphoseek versus vital blue dye, a long-standing, FDA-approved, on-label agent for lymphatic mapping and appropriate requisite "Truth Standard" comparator for registration purposes.
