Patient demographics may plausibly influence the quality of monitoring of psychotropic medication [ 19], but to what extent this would be driven by variable engagement with healthcare by patients and the behaviour of clinicians is uncertain.
In forested ecosystems, management decisions are driven by variables such as forest composition, forest structure (both vertical and horizontal), and other ancillary data (i.e., topography, soils, slope, aspect, and disturbance regime dynamics).
"The fact is, the rates are driven by variable practice, not by risk factors, and that cannot continue".
The observed adaptation was driven by variable quantitative changes of the different separately studied life history traits (i.e. fecundity, longevity, sex-ratio, time to maturity).
More common is however the late onset form (loAD) of AD that comprises 95% of all cases and is driven by variable combinations of genetic and environmental risk factors (Sananbenesi & Fischer, 2009; Goate & Hardy, 2012).
Nevertheless, this relationship could also be driven by unmeasured variables such as the average distance between home and school [ 26, 29] or neighbourhood walkability [ 17, 30] which are known to influence travel behaviours.
Additional analyses suggest that these results are quite robust and are unlikely to be driven by omitted variable or selection bias.
This result leads us to believe that the positive effects on earnings are unlikely to be driven by omitted variable bias.
In this scenario, S/Cl ratios across the deposit would be driven by the variable reactivity of tephra to SO2, mediated by temporal changes within the eruption and by tephra sedimentation patterns.
For instance, both of these variables may be driven by some unmeasured variable.
