Positive-results bias, a type of publication bias, occurs when authors are more likely to submit, or editors are more likely to accept, positive results than negative or inconclusive results. [15] Outcome reporting bias occurs when multiple outcomes are measured and analyzed, but the reporting of these outcomes is dependent on the strength and ...
An asymmetric funnel indicates a relationship between treatment effect estimate and study precision. This suggests the possibility of either publication bias or a systematic difference between studies of higher and lower precision (typically ‘small study effects’). Asymmetry can also arise from use of an inappropriate effect measure.
Systemic bias: This page outlines real, useful information about systemic bias on Wikipedia. We are aware that we have biases, and we do what we can to combat them. One against many: This page gives advice for dealing with situations where one editor wants to make a change but multiple editors oppose the change.
Are there ways to reduce implicit bias? Adults harbor an untold amount of bias smog. But all is not lost if you want to be more open-minded or be a true ally. Being self-aware of your bias and ...
Publication bias is a type of bias with regard to what academic research is likely to be published because of a tendency among researchers and journal editors to prefer some outcomes rather than others (e.g., results showing a significant finding), which leads to a problematic bias in the published literature. [139]
The problem of publication bias is not trivial as it is suggested that 25% of meta-analyses in the psychological sciences may have suffered from publication bias. [120] However, low power of existing tests and problems with the visual appearance of the funnel plot remain an issue, and estimates of publication bias may remain lower than what ...
Selection bias is closely related to: publication bias or reporting bias, the distortion produced in community perception or meta-analyses by not publishing uninteresting (usually negative) results, or results which go against the experimenter's prejudices, a sponsor's interests, or community expectations.
Researchers assessed the studies for risk of bias in five different domains. The final review included data from eight publications covering seven randomized controlled trials. In all, they were ...
