As for drug use behaviors, although this relied upon self-report, previous work has shown a high correlation between self-report and other measures, such as heroin-confirmation urine tests, in these settings (26).
Although this process relies on an interpretivist approach, the codes were re-examined in relation to the quantitative data to ascertain proximity to the research questions and provide an arguably meaningful interpretation of the interview data.
Intergenotype recombination in HCV has been related to homologous recombination during minus-strand synthesis via template switching [23], although this proposal relies on the presence of two hairpin structures in the vicinity of the inferred breakpoint of recombination.
Although this research relies on the documentation of the original datasets, there may have been bias in the sample collection phase.
Although this estimate relies on several tenuous assumptions it serves to show the limitation of extrapolating mtDNA contamination estimates to the nuclear genome.
Although this method relies on the reliability of chemical reactions or pathway-map network data employed, the framework is very simple.
Genomic epidemiological approaches currently represent a promising route forward allowing detection of signatures of selection associated with drug resistance [ 6], although this approach relies on identification of linkage disequilibrium which is known to be of variable strength [ 7].
It is important to note that although this study relies upon the links we created in our previously published ontology-enrichment work, our methodology for nonalignment identification is not limited by the specific relationships we chose to use.
Although this study relies on parametric methods to generate conclusions, non-parametric Wilcoxon rank sum testing was also employed to provide sensitivity testing for robustness and reliability of results.
Although this study relies on the continuous BMD exposure variable for its primary analysis, we calculated adjusted mean percentage mammographic density in each quartile of lumbar spine BMD and total hip BMD as a means of illustrating the magnitude of the association between mammographic density and BMD among women who had not recently used postmenopausal hormones.
As with pasta sauces, in many cases the suggested serving contains less, although that relies on the consumer following the guidance.
