Methodological considerations, such as including appropriate control groups and measuring postfailure outcomes, are stressed, and directions for future research are highlighted.
However, several studies failed to demonstrate a link between contraceptive use and HIV-1 acquisition or transmission, and interpretation of many studies limited by methodological considerations, such as infrequent measurements of contraceptive exposure and HIV-1 status.
Besides methodological considerations, such as quantitative versus semi-quantitative methods of mRNA determination, other factors may account for the discrepancy with their findings.
Studies were ranged according to level of evidence by the authors based on methodological considerations, such as sample bias, lack of comparison groups, and design.
Other mechanisms for regulation as well as methodological considerations such as the proportion of positive tumor cells identified and the sensitivity of the mutation detection can also contribute to the variation reported.
Unfortunately, these reviews are not based on all of the available evidence, generally only explore the prevalence of high prevalence disorders, such as mood disorders, anxiety disorders and substance use disorders, and are unable to explore the degree to which prevalence estimates of co-morbidity fluctuate as a function of clinical and methodological considerations, such as gambling severity.
With the growing emphasis on observational analyses in health care, the radiation oncology community must possess a sophisticated understanding of the methodological considerations of such studies in order to evaluate evidence appropriately to guide practice and policy.
However, results accuracy crucially depends on methodological and empirical considerations such as: i) presence of spatial latent component (spatial autocorrelation); ii) temporal breaks related to different periods over which the infrastructure is built; and iii) heterogeneity of the effect along the line and stations.
Perhaps more damningly, Bonß 1993 argues that this failure comes from faults internal to Horkheimer's methodological and epistemological considerations such that "the interdisciplinary claim amounts to no more than an external formula for integration" (p. 118).
It also discusses some methodological considerations when performing such studies.
As such, we propose methodological considerations for the behavioral assessment of hippocampal function in developing rats that take into account animal size, growth rate, and sensory and motor ability.
