The phrase "a more restrictive threshold" is correct and usable in written English.
It can be used when discussing criteria or limits that are tighter or more limiting than previous standards or measures.
Example: "The new policy sets a more restrictive threshold for eligibility, ensuring that only the most qualified candidates are considered."
Alternatives: "a tighter limit" or "a stricter standard".
The value of the E-field is 27.1 V/m; this involves that the more restrictive threshold of 3 V/m, established in the International Electrotechnical Commission Standard of Electromedical Devices [ 8], is exceeded.
The LO-mTLE group showed more varied levels of BC at the different statistical thresholds for the non-ictal hippocampus, with low values at the more restrictive threshold (5, 10 %) and higher values for the less restrictive thresholds (30, 35%%).
In the cases of very small distances from the tested device, the highest level of E-field strength exceeds the more restrictive threshold of 3 V/m that is established in the International Electrotechnical Commission Standard of Electromedical Devices [ 8].
For the identification of overrepresented binding sites in large gene sets, it is advisable to use more restrictive thresholds (a smaller number of random matches).
For multiple comparisons, a more restrictive significance threshold for p value was used by a Bonferroni's correction for multiple comparisons.
Thus, we choose to set a more restrictive significance threshold (than p < 0.05 corrected) at p < 0.001 uncorrected for multiple comparisons.
Using a more restrictive transfusion threshold as suggested by Paone and colleagues [ 31], who transfused cardiac surgical patients in the ICU at an Hct of less than 20% without observing any adverse effects on outcome.
As suggested by Field (2009) [ 31], a sample size of 50 individuals can be satisfactory for factor analysis, if more restrictive thresholds for interpretation of factor loading are employed.
The use of institutional transfusion protocols was associated with more restrictive thresholds, especially in grade 1 SAH patients (mean Hb with transfusion protocol, 7.70 g/dL (95% CI, 7.54 to 7.87); mean Hb without protocol, 7.98 g/dL (95% CI, 7.80 to 8.16); P = 0.01).
However, if a more restrictive p-value threshold of 0.01 is established, only ten SNPs, located in six genes (one in each of ADAMTS20, TYR and SILV-CDK2; two in each of KIT and MYO7A; and three in SLC45A2) on six individual chromosomes constituted the top ten MM associated SNPs in our Spanish population.
