The phrase "a specified margin of" is correct and usable in written English.
It can be used when discussing a defined or particular amount of difference or allowance in various contexts, such as finance, statistics, or project management.
Example: "The project was completed within a specified margin of error, ensuring the results were accurate."
Alternatives: "a defined range of" or "a designated allowance of".
Davis, a Democrat, wants FERC to return to the traditional way of setting electricity rates, in which generators were allowed to recover their costs plus a specified margin of profit.
Facilitated access will be deemed not inferior to face-to-face treatment at a one-sided α of 2.5% if the difference between the proportions of risky drinkers in the facilitated access group and the face-to-face BI group is below a specified margin of non-inferiority of 10%.
Proportions of risky drinkers in each group will be calculated and non-inferiority assessed against a specified margin of 10%.
Assessment of non-inferiority of canagliflozin to sitagliptin was based on a pre-specified margin of 0.3% for the upper limit of the two-sided 95% CI for the comparison.
ILPS was found to be non-inferior to glargine in change in HbA1c from baseline to the 24-week endpoint based on a pre-specified margin of 0.4%, although glargine was associated with greater HbA1c change and lower endpoint HbA1c.
The difference among treatment groups was often assessed using a non-inferiority analysis in which the lower bound of the confidence interval for the difference in proportions of successfully treated patients was compared using a pre-specified margin of difference usually between 10 and 20%%.
Power calculation indicated that 168 patients per treatment arm would provide 80% power to determine if ILPS is non-inferior to glargine when added to OAMs and exenatide BID, with a pre-specified margin of 0.4% difference in least-squares (LS) mean HbA1c change, assuming no true difference, 15% dropout rate and a standard deviation (s.d). of 1.2 at a significance level of 0.05.
The lower bound of the 95% C.I. on the proportion of concordant positivity calls for CMV (97.2%) and CEF (89.5%) were both greater than the pre-specified margin of 70%.
However, the non-inferiority claim implied that the upper limit of the 95% confidence interval (CI) for the HR of the primary efficacy outcome was less than this pre-specified margin of 2.0.
At 52 weeks, canagliflozin 100 mg and 300 mg demonstrated non-inferiority to sitagliptin 100 mg in HbA1c-lowering effect (upper limit of the 95% CI less than pre-specified margin of 0.3%; Fig. 2b, c; Table 2).
Hida and Tango [ 7] proposed a test procedure for assessing the assay sensitivity with a pre-specified margin defined as a difference between treatments in the presence of homoscedasticity.
