In order to establish where clinical risk may exist, the frequencies of critical errors/omissions achieved by all candidates within each station were recorded as a percentage of the total number of criticals assessed (table 2).
A biallelic model is justified by the extreme rarity triallelic variation at nucleotide sites, and in the unusual situation in which such a situation did exist, the frequencies of the two most common alleles and of the error rate would be slightly overestimated.
Many empirical examples exist, where the frequency of a particular trait or allele changes along the gradient in a clinal manner (see e.g. [ 10, 11]), and examples exist too for ecotype formation along environmental gradients [ 12, 13].
For breast and cervical cancer screening examinations, explicit policy rules exist detailing the frequency of screening examinations depending on age limits, cancer history of first-degree relatives and screening examinations in previous years.
Few data exist concerning the frequency of missed results and associated treatment delays within the Veterans Health Administration (VA).
Two retrospective investigations [ 39, 40] have suggested that a dose-response relationship may exist between the frequency of exposure to severe hypoglycemia and the subsequent risk of dementia.
Sabath et al. write: "If evolvability is selected for, the expectation is for a positive correlation to exist between the frequency of an overlap phase and its evolvability.
If evolvability is selected for, the expectation is for a positive correlation to exist between the frequency of an overlap phase and its evolvability.
Limited data exist on the frequency of a clinical diagnosis of MA in the pediatric population with type 1 diabetes in the U.S. Our aim was to use the data from the T1D Exchange clinic registry to assess factors associated with MA in 7,549 children and adolescents with type 1 diabetes.
Comparing the groups of patients who are drug resistant and who respond well to AEDs, no statistically significant differences have been found to exist between the frequency of occurrence of alleles *1/*3 and *3/*3 between the study groups (children with epilepsy) and control (P = 0.70).
