Thus, more studies are needed to improve the conclusions on this subject for ESRD, since the cross-sectional characteristics of this study compromise the data inference.
Systematic review procedures address study credibility by assessing internal validity or "risk of bias" — the assessment of whether the design and conduct of a study compromised the credibility of the link between exposure/intervention and outcome.
A very low prevalence of persistent CMD in the current study compromised the power to detect any meaningful effect.
For the same reason as well as illegitimacy of sexual relation and having prior to marriage children, the population of present study compromised married women with PCOS.
Exclusion criteria applied in this study were compromised quality of Pap smears, patients previously vaccinated with anti-HPV vaccine, cervical neoplasia or existence of other malignancies, surgery related to the uterine cervix, an immunocompromised state, genital warts, or pregnancy.
This study is compromised by its observational design, the regional context and the exclusion of non-Swedish speaking women, which makes it difficult to generalize the findings to all women.
While the power of this study is compromised by the small sample size, the analysis did demonstrate a link between specific cytochrome p450 polymorphisms and an increased rate of TGCT development.
However, as acknowledged by the authors, this study was compromised by the limited material available (Haynes and Heinly, 1995) and, thus, although the timing at which subsequent stages in T-cell development are first observed has been determined (Res and Spits, 1999), the stage at which the earliest hematopoietic cells colonize the human thymus remains unknown.
Funnel plots and the Egger's regression asymmetry test (data not shown) did not reveal evidence for publication bias, although small number of studies compromised this analysis.
We cannot completely exclude that sample sizes in this study may compromise our ability to accurately assess historical levels of genetic diversity, but we believe that the third scenario is the most likely.
