The normalization controls for individual differences in baseline mean and variability that can affect the amplitude of the stimulus-elicited HR changes [8], [69].
Reasons for an inability to maintain a stable INR include patient non-compliance with dietary restrictions, missed doses, and failure to routinely monitor and thus adjust doses when needed, drug drug interactions, and genetic variability that can affect warfarin metabolism [ 16].
This fact, as reported by Gonzalez et al. [14], could be due to the high variability of influent wastewater composition over the year and to the wide range of variables that can affect the sludge-treatment process.
Low-frequency variations, on the other hand, have received less attention, especially in association with multi-decadal cycles that can affect variability trends of precipitation in the long term.
However, genetic variability is not the only factor that can affect functional activity of drug-metabolising enzymes; gender, age and co-medications can all play a role in variable CYP expression.
The effect of the ionosphere is critical in high-accuracy GNSS applications, due to its high variability and to disturbances such as scintillation that can affect the satellites signals propagation.
This study has shown that an individual's life history with noxious stimuli is a potential source of variability in adult pain experiences and one that can affect sensorimotor processing, pain sensitivity and other behavioral outcomes.
Goldberg was interested in diseases that can affect how people control variability in their thoughts or actions.
Modes of inheritance [ 6], mutation rate [ 7], mutation models [ 8, 9], recombination [ 10], and natural selection [ 11] are important factors that can affect estimates of genetic variability, and consequently measures of population differentiation [ 12].
However, the individual's life history with noxious stimuli has often been overlooked as a potential source of variability in an adult pain experience; yet it is one that can affect sensorimotor processing, pain sensitivity and other behavioral outcomes.
Blood pressure variability as estimated by SD is an important measure and researchers in the area should be familiar with the average magnitude of that variability, 14 mmHg for systolic and 8 mmHg for diastolic, and the factors that can affect it.
