The phrase "a specified cut off value" is correct and usable in written English.
It can be used in contexts where a particular threshold or limit is defined for a measurement or decision-making process.
Example: "In our analysis, we will only consider data points that exceed a specified cut off value to ensure accuracy."
Alternatives: "a defined threshold" or "a designated limit".
Excluding all observations greater than a specified cut-off value is the second option.
Subsequent statistical tests were carried out for the duck samples using GeneSpring 7.2 (Silicon Genetics) to determine all genes differentially regulated to a specified cut-off value (p = 0.05).
The remaining 67 participants were used to calculate the window periods corresponding to specified cut-off values and to calculate cut-off values corresponding to specified window periods.
Data points with residuals outside the specified cut-off values (2.5 and 2 stdev) are highlighted in the data screening plots (Figs. 3 5).
A statistical test is used to estimate a p value and a specified cut-off is chosen, such that below it protein changes are deemed significant.
In addition, receiver operating characteristic (ROC) curves were obtained to specify cut-off values of ONSD and eICP for the prediction of elevated ICP.
In exploratory analyses, potential differences between the ACWY-TT and the MenC-CRM groups were highlighted if the standardized asymptotic 95% CI for the group difference in the percentage of toddlers with titers above the specified cut-offs did not include the value 0, or if the 95% CIs of the GMT ratio between the two groups did not include the value 1.
As specified in the protocol, potential differences between the ACWY-TT and the Men-PS groups were highlighted in exploratory analyses if the standardized asymptotic 95% CI for the group difference in the percentage of toddlers with titers above the specified cut-offs did not include the value 0, or if the 95% CIs of the GMT ratio between the two groups did not include the value 1.
The World Bank has proposed a similar definition but has not specified a cut-off value [ 81].
Masked reads were then searched against the non-redundant NCBI database (http://blast.ncbi.nlm.nih.gov, release of March 2009) and the UniProtKB/Swiss-Prot Toxin Annotation Program database (http://us.expasy.org/sprot/tox-prot), using BlastX and BlastN [ 112] algorithms, specifying a cut-off value of e-03 and BLOSUM62 as scoring matrix.
