Sentence examples for power stratification from inspiring English sources

Interestingly, significant differences in evoked responses did remain after alpha power stratification and showed a morphology very similar to the original data.

The same trials (stratified data) were selected to recalculate the graph theoretical measure node degree for the right auditory cortex to test whether network contrast effects persist after alpha power stratification.

Statistical re-analysis of power, evoked response, and graph theoretical results after alpha power stratification was conducted by selecting the data point with the maximum statistical value in time frequency grid space for the original data (before stratification) and calculating a dependent sample t-test.

The failure of researchers to replicate genetic-association findings is most commonly attributed to insufficient statistical power, population stratification, or various forms of between-study heterogeneity or environmental influences.1 Here, we illustrate another potential cause for nonreplications that has so far not received much attention in the literature.

However, more SNPs had allele frequency ratio with the same trend as the sample size ratio and hence contributed more to a reduction in power when stratification correction was applied.

For the causal-StruInfo SNPs in our simulation (see Methods for definitions of these simulated SNPs), some of the SNPs for which the allele frequency ratio was the inverse of the sample size ratio may have contributed to an increase in power after stratification correction was applied.

However, because of the limited power after stratification, these results must be cautiously interpreted.

As mentioned earlier, factors that may significantly contribute to inconsistencies in genetic studies of osteoporosis include inadequate statistical power, population stratification, genetic heterogeneity, experimental errors, and limited coverage of genomic regions [ 27].

This observation indicates that special attention has to be paid to the population's allele frequency spectra when powers for stratification correction strategies are compared.

This trial was not prospectively powered for stratification by ACE genotype, so although post hoc analysis did not identify a genotype-specific influence on quadriceps function, this method of stratification would be an important consideration for future studies.

Concentrating only on providing access to dental care may detract from the more powerful effects of social stratification, power differentials, and the understanding of different cultures and their beliefs and practices that contribute to oral health.
