The subjective context necessarily involved a subjective rating, whilst the classical context did not, making it difficult to compare these conditions directly.
Since the height distributions of the two reference samples are not comparable, it is difficult to compare the corresponding height depended 50th, 90th and 95th blood pressure percentiles directly, therefore, the expected SBP and DBP of US counterparts with the median height of Chinese reference population were computed based on the equations.
However, current methods employed to evaluate oxygen-evolving catalysts are not standardized, making it difficult to compare the activity and stability of these materials.
This specificity not only makes it difficult to compare data from different systems, as it can influence the accuracy and reliability of the recorded information, but also causes some systems to be inappropriate for particular objects.
Given that a phenotypic ontology is not available, it is difficult to compare conditions.
Currently, since air sampling protocols are not standardized, it is difficult to compare results from different studies [ 18].
This decrease of mortality not only makes it difficult to compare recent studies to trials performed several years ago, it also has to be taken into account for calculations of trial sample size when considering mortality as an end-point.
Regarding tumor site, although more patients with a tumor in the oral cavity indicated that they had moderate to severe pain, this difference was not significant and is difficult to compare with prior results because of the lack of earlier studies regarding the impact of pain intensity in pretreatment HNSCC patients.
In addition, due to different variant tests reported in each paper (a total of 16 combinations for four amino-acid substitutions) and different expression and assay systems used between different laboratories, the results were not consistent and were difficult to compare (Hanna et al, 2000; Li et al, 2000; McLellan et al, 2000; Shimada et al, 2001; Aklillu et al, 2002).
However, it is unclear how these results relate to our study, as in those previous studies cells were identified using single staining of consecutive sections and the positive cells in the overlying sections were not quantified, making it difficult to compare these contradictory results with the results of our study [ 18, 19].
Yet again, these values are low, indicating that the topology of relevance networks is sensitive to uncertainty in the data (note that r and τ are not directly comparable, so it is difficult to compare the relative tolerance to data uncertainty of relevance networks and GGMs).
