Two of these studies [132, 133] found an identical mortality, while the third [134] showed excess mortality in a hemodialysis group, but this study suffered from bias in the distribution of the patients by disease severity.
Thus there was no systematic bias in the distribution of recordings from the various groups across cortical layers.
However, compared to non-interacting proteins, the interacting proteins exhibit a significant bias in the distribution towards positive correlation.
This suggests that it is not feasible to apply the same standard dose to different routes, as this could create bias in the distribution of BXD incubation times.
We observe a bias in the distribution of the differently tagged primers that is dependent on the 5' nucleotide of the tag.
Extensive theoretical work [15] [20] has shown that surveys of ascertained SNPs may introduce a bias in the distribution of allele frequencies, linkage disequilibrium and polymorphism levels and, therefore, affect population genetics inferences.
We further show that this bias - rather than a bias in the distribution of natural spectra or in the cone response functions per se - is sufficient to explain the HK effect.
We checked for a potential sampling bias in the distribution of genetic diversity by plotting the mean intraspecific genetic distance between haplotypes against the number of individual analysed and tested the significance of the relationship using a covariance analysis as implemented in Statgraphics [45].
Second, amplification should not induce a bias in the distribution of the product DNA.
Neither did they find a bias in the distribution of the polymorphism among CLL cases.
This result supports a moderate β strand bias in the distribution of Leu.
