The relative contribution of each variable to this pattern cannot be ascertained due to colinearity between variables.
The recruitment of k-mers from one contig to an unrelated contig (as shown in Fig. 6) presents a severe problem to NGS assemblers, since the position of k-mers cannot be ascertained prior to assembly.
The giant azhdarchid Hatzegopteryx appears to have a particularly wide skull (500 mm across the quadrates), but the relationship between this and skull length cannot be ascertained due to its fragmentary nature.
Although the clinical significance of these unrecognized mutations cannot be ascertained due to the cross-sectional nature of our study, a potential clinical implication here is that conventional genotype might be adequate for a subset of patients with well-characterized antiretroviral treatment histories and known longitudinal HIV genotypes.
The clinical significance of these unrecognized mutations cannot be ascertained due to the cross-sectional nature of our study; however, we can conclude that the majority of unrecognized resistant mutations correlate with historical antiretroviral use rather than to the failing antiretroviral drugs.
We therefore reasoned that to conduct a comprehensive investigation of breast cancer aetiology, a cohort design is needed, in particular to ascertain factors that cannot be ascertained retrospectively, but also to avoid recall bias and imprecision.
This can lead to counseling dilemmas and parental anxiety, especially in low-risk pregnancies, because the associated neurodevelopmental phenotypes cannot be ascertained prenatally and it is difficult to quantify the risk to the fetus.
The degree of stenosis cannot be ascertained with accuracy without reference to normal baseline tracheal measurements.
Particularly, because the denominator data (numbers of travellers) cannot be ascertained, it is not possible to calculate incidence rates.
It may be that dignity is in the final causal pathway between freedom and health, but this cannot be ascertained with the data available to us.
