However, there is considerable geographic variability in the impact of these vaccines on other disease endpoints and in other age groups.
There is enormous variability in the impact of social interventions across different populations, different organizational contexts, and different community settings.
The considerable heterogeneity of effect sizes across studies, however, underscores the variability in the impact of the illness on cognitive functioning.
Future studies could assess how important it would be to incorporate variability in the impact of an exposure through direct contact with a varicella case, based on characteristics of both the exposed and the infectious person (e.g., age, comorbidity).
The resulting mortality estimates are discussed with respect to available information on possible sources of mortality, as these are suggesting a high variability in the impact of 'critical periods' on larval survival.
Fukuda and Vogel (2009) recently demonstrated that there are substantial individual differences in the degrees to which salient irrelevant singletons affect search, though little research has been conducted examining variability in the impact of a distractor that is less salient than the target.
The post-use of HWPs is "the single significant source of variability in the GHG impacts of the wood product life cycle" [19].
We complement binary treatment analysis with continuous treatment analysis to understand not only the impact of being in the program but also the variability in impacts by the extent of treatment.
However, significant species-specific variation between rodents and humans as well as genetic variability in humans impacts the extrapolation to the clinical situation (Hartung 2009).
We expected a strong seasonal pattern of reproduction due to the predictable seasonality of extrinsic variables but, in addition, we predicted that inter-annual variability in the environment would impact the reproduction rate.
