The range of experience among physicians was also broad which, although providing good coverage of routine clinical practice, could be complicated by differences in attitudes between physicians of different generations.
However, it is also important to note that the direct comparison of the findings from different groups can be complicated by differences in experimental conditions, for example the type of PFSPs used, which can be affected by many factors including the sonication conditions used for the preparations.
Any movement between places is significant (Wakefield et al. 2001); pollution and other hazards that form concentrations can be modified as they move through the environment and affect different places in different ways, whereas spatial patterns in risk will be complicated by differences in susceptibility and by variations that arise simply because populations are unique to particular places.
The actual potential for reuse across disciplines may be complicated by differences in disciplinary preferences in relation to preferred types and formats of resources (Littlejohn & Margaryan, 2006) and variances in pedagogic approaches (HEA & Jisc, 2009; Russell, 2005).
It should be noted that comparison of frequency of occurrence data between prey species may be complicated by differences in the sensitivity of prey-specific PCR tests (i.e., if the amount of prey DNA in many samples is close to the sensitivity limits of the PCR tests, then the importance of prey targeted by the least sensitive test will be underestimated).
Secondly, the interpretation of transcriptome data obtained from the generally employed shake-flask cultivations is likely to be complicated by differences in specific growth rate, carbon catabolite repression, nitrogen catabolite repression, and more generally continuous changes in environmental conditions.
Again, direct comparison is complicated by differences in methodology and the differing definition of the tumour cohorts.
Comparing data on vitamin D levels from different observational studies is complicated by differences in definitions and diagnostic methods.
Variability between HPV prevalence in different populations has been highlighted in numerous studies but is complicated by differences in study design, sample collection and methods used for HPV detection and typing.
But the designer's problem is complicated by differences among drivers, he said.
As the sanctions kick in, rising month by month, I think we'll get businesses calling us and saying, 'Get this bill passed, get this bill passed".' Yet the chances that any legislation will be enacted are complicated by differences between the bills.
