The phrase "a given prevalence" is correct and usable in written English.
It can be used when discussing a specific level or rate of occurrence of something within a particular context or study.
Example: "In this research, we will analyze the effects of a given prevalence of anxiety disorders among adolescents."
Alternatives: "a specific prevalence" or "a certain prevalence".
Similarly, although there was considerable variation due to relative rates of direct versus indirect transmission, we found that increasing prion survival rates generally increased R0 for a given prevalence growth rate (Figure 7; for every 1 year increase in prion half-life, we see an absolute increase of 0.29 in R0 [95%CI = 0.21 0.37; R2 = 0.21, F = 54.3, df = 202, p<0.01]).
Our method is based precisely on determining which such distribution (for a given prevalence and heritability) would allow the best predictive accuracy.
Furthermore, we performed a model calculation to determine how elastography could affect the proceedings in population screening with a given prevalence of BI-RADS®-US 3 lesions.
On this basis, sensitivity was calculated as the percentage of districts in a given prevalence category that were correctly classified as such, and specificity was calculated as the proportion of districts not in a given prevalence category correctly classified as such.
Although 2,195 references do not appear to be a small sample size, for a given prevalence of 0.0027% of relevant references in the PubMed/Medline population, the sample is still small.
In our use of the scenario tree method, we also aimed at calculating a sample size to demonstrate disease freedom for a given sensitivity and at a given prevalence.
As we mentioned in Equation 2, the optimum CT should correspond to a detection that gives prevalence value P equal to its level Q.
Scenario tree modelling is used to calculate the sensitivity of a SSC for a given design prevalence and sample size [ 3].
For a given disease prevalence at high values of heritability, the power of both RPM and KWII was greater than 95%.
For a given prior, prevalence, and parameters and τ we optimized the consistency boundary c together with α0 and r to maximize the utility function 2013.
However, within a given country, the prevalence may also vary among cat populations.
