Consequently, inter-observer and intra-observer variability that may be affected by many factors such as case difficulty, radiologist's experience, varying practices and others, is a great challenge in mammographic screening and has been shown to be a great problem for SFM as well as FFDM [ 4, 5].
As outlined, the variability in obstetric intervention may be affected by factors such as user expectations, unnecessary or inappropriate assistance, the culture of medical practice, the organisation of care provision and available resources.
The variability in the small measurements may be affected by the resolution of the measuring system.
However, it should be noted that the tidal structure may be subject to long-term variability and that its statistics may be affected by the partial sampling that arises from the use of a single satellite, as explained in what follows.
Outcomes may be affected by variability in the timing of interventions, in addition to variability in the quality of interventions.
We preferred this methodology to symptom change cut-offs, which are arbitrary, may be affected by variability in baseline symptom severity and are not intuitively understood by clinicians.
As a longitudinal retest design may be affected by variability in human motion which occur naturally over time or were due to the psychosocial effects of repeated testing it was important to establish the normal variability over time.
On the other hand, PRO measures may be affected by interpatient variability if the instrument is not easily understood and completed by patients.
Efficacy of and/or tolerance to voriconazole may be affected by great variability in blood levels caused by nonlinear pharmacokinetics, polymorphism of cytochrome CYP2C19, drug-drug interactions and hepatic dysfunction [ 75- 77].
