As both models compare a number of independent variables, the problem of multiplicity – that is, testing multiple hypotheses – might undermine the analysis by increasing the likelihood of type I error (Benjamini & Yekutieli 2001).
Second, we showed that freeze thawing meat samples did not undermine the analysis, an important point to establish since the supply chain involves both chilled and frozen meat.
This is an impressive piece of work because it analyzes the channel in a lipid bilayer environment rather than in detergent micelles, and because the authors use photobleaching to ensure that they are studying channels with one donor and one acceptor, thus avoiding complications that might otherwise undermine the analysis.
But there is a central contradiction in her logic that undermines the whole analysis.
The serious issue in not distinguishing between paralogous flagellin genes (i.e., FlaA and FlaB) undermines the entire analysis of this paper and its interpretation.
As I discuss below, the few historical exceptions to this rule do not undermine the constitutional analysis.
Although viral metagenomics approaches have both expanded our view of global viral biodiversity, and paved the way towards a better understanding of viral ecology and evolution, several methodological biases undermine the effective analysis and taxonomic assignment of the sequence reads and contigs that have been generated using these approaches11,19,20.
The absence of some articles from this map is unlikely to undermine the overall analysis, although the focus on English literature does affect assessment of where such work has been conducted, and, perhaps, of approaches to this work.
The analysis undermines not only the claims made by GOP leaders, but also shows that their bill could, by undoing what is perhaps the Affordable Care Act's single most popular provision, throw consumers back into insurance markets where their ability to purchase affordable insurance would depend on their health.
That many of the largest trials contributed such little weight to the analysis undermines our confidence in the results.
