We conclude by assessing some possible macrolevel explanations for this variation, including per capita gross domestic product, tax rates, unionization, country-level regulations, earnings inequality, and the regulation of weekly work hours.
The CTA appearance of this variation includes the origin of the posterior cerebral artery from the ICA as well as the absence of the ipsilateral P1 segment of the posterior cerebral artery connecting to the basilar artery.
Multiple reasons have been described for this variation including differences in inclusion/exclusion criteria, differences in the setting in which the CPR was performed and problems with definitions of common variables [2, 3].
Factors affecting this variation include "the number of voters represented, whether the system is unicameral or bicameral, and whether members represent a defined constituency or are elected on a party list", it added, repeating caveats first expressed by the Senior Salaries Review Board in 2007.
c) Factors contributing to this variation include the pain threshold of the woman, the radiographer's sensitivity for pain expression, the uncertainty or inaccuracy in estimating the pressure on the breast, the radiographer's opinion of what is a good compression, and local conventions.
The nature of this variation, including its tissue-specific nature, and the role it may play in human phenotypic variation and disease is still poorly characterized.
Key factors in this variation include sample preparation, the extent of allele overlap between the genotypes contributing to the evidence, the suspect genotype, and allele population frequencies.
This variation includes prophages, transposable elements, and accessory genes (see 'Glossary'Glossary
Examples of this variation include the addition of complement or reporting sera dilutions before or after the addition of virus.
