The phrase "risk of variation" is correct and usable in written English.
You can use it when you want to describe something that could have several different outcomes, or that could vary based on certain factors. For example: "There is a risk of variation in the results of the experiment depending on the conditions of the laboratory."
We conclude that a multi-model screening system combining the use of cell cultures in vitro and the hDMD/mdx mouse in vivo could reduce potential risk of variation in efficiency between cell culture and in vivo and represents a more systematic approach for identifying AOs of high efficacy, thus better suited to meet the regulatory requirement for AO drug development.
19 Most drug-discovery programs actively strive to develop compounds with sufficiently high solubility and permeability in order to reduce the uncertainty and risk of variation in exposure.
By taking local requirements into account there is a risk of variation in return of results requirements at the country or even study site level.
Even if this is the case, however, the callus phase must be very short, and according to Jähne and Lörz (1995) [ 18] a short regeneration time diminishes the risk of variation.
This indicates that a low-tech greenhouse diminishes the risk of variations among price paths in different years, whereas a high-tech greenhouse covers better the "weather risk".
Criteria 2 4 were set to minimize the risk of variations in oxygen consumption due to nonhemodynamic factors.
Fourth, there is likely to be some variation in relative risk because of variation in the calculation of risk statistics; studies reported relative risks, odds ratios, and incidence ratios, and simple presentations of incidence.
Risks of variations related to potential matrix effects are therefore reduced, as well as probable variations related to the digestion steps.
Our findings show that genetic variation in the α-synuclein gene is associated with sporadic MSA, and suggest that susceptibility to MSA-C may be the greater risk of SNCA variation.
This analysis suggested frequent influence on risk of genetic variation in loci encoding for "driver kinases" (i.e., kinases encoded by genes that showed higher somatic mutation rates than expected by chance and, therefore, whose deregulation may contribute to cancer development and/or progression).
Since payoffs for each individual were derived in terms of risk of death, variation among soldiers' preference orderings was unlikely.
