However, if there are a considerable number of risk factors which are possibly correlated, it is obvious that unadjusted AFs from bivariate analyses may be biased providing an overestimation of the preventive potential and adjusted AFs should be rather considered.
On one hand, removing female information did not result in a loss in accuracy, which means that this additional information was (at least partly) biased, providing as much noise as useful information.
However, in the main, studies demonstrated a low risk of reporting bias, providing results for all outcomes that they measured.
Tetrodes allow the separation of neurons within such a cluster and therefore may avoid such biases, providing a more sensitive index of neuronal activity that could explain the difference between past studies and the present findings.
Both appeared to be at a comparatively low risk for bias, providing a clearly defined research question, search strategy, inclusion and exclusion criteria, and description of outcomes.
CBM procedures are designed to augment or attenuate cognitive processing biases, providing not only a method of studying the causal relationship between attentional bias, craving and relapse, but also a potential treatment for attentional bias in clinical populations.
We show here for the first time how fog biases speed perception, and we reveal the perceptual mechanisms underlying this bias, providing important insights into the human visual system.
The results show a positive correlation between tRNA gene copy number and codon usage bias providing further evidence for translational selection; only one T. brucei tRNA gene fails to display a matching bias in copy number.
Facilitators identified included: raising awareness of the effects of publication bias, providing incentives to make data publically available, and implementing laws to enforce prospective registration and reporting of clinical trial results.
Despite a lack of information about genotyping quality control (QC), and some risk of population stratification, this large effect size confers some protection from bias, providing Venice grading BBB, or moderate epidemiological credibility (Table 2).
Gene expression levels are measured as probe-target hybridisation intensities, and all values are background corrected, with the inter-array quantile normalised to remove systematic biases, providing relative rather than absolute gene expression levels [ 9].
