However, the above mentioned studies are limited because they applied a cross-sectional and not a longitudinal design.
All the above mentioned studies have however limited their attention to the CD rate.
The above mentioned studies have been limited by the use of geometric parameters and, in particular, the maximum diameter of lumen alone as factors contributing to the rupture of an AAA.
One other study evaluated the combined relationship between the three molecular markers and HPV status using immunohistochemistry (Wilczynski et al, 1998), but similar to the earlier mentioned studies, their analysis was limited to tumours that arose in the tonsils.
However, almost all mentioned studies were cross-sectional in nature (i.e., no longitudinal follow-up), limiting the interpretation of age-specific HR-HPV prevalence in China.
However, it should be noted that the above mentioned studies used different definitions of outcome, study population, assessment methods, and confounding factors, thus limiting the feasibility of inter-study comparisons.
MR: Now, you mentioned studying with Paul Simon.
Since the frequency of RLS sufferers could not be determined in the previous mentioned study, the results cannot be translated to a RLS population and the comparability of these results to our study is limited.
The studies mentioned have limited case numbers in comparison with the present study, which confirmed an increased risk.
With the exception of one recent study that measured BPA concentrations in the blood of 300 women and their fetuses (Lee et al. 2008), the studies mentioned above are limited because of their relatively small sample sizes.
