Error Rates, Decisive Outcomes and Publication Bias with Several Inferential Methods

Erratum to: Error Rates, Decisive Outcomes and Publication Bias with Several Inferential Methods.

BACKGROUND Statistical methods for inferring the true magnitude of an effect from a sample should have acceptable error rates when the true effect is trivial (type I rates) or substantial (type II rates). OBJECTIVE The objective of this study was to quantify the error rates, rates of decisive (publishable) outcomes and publication bias of five inferential methods commonly used in sports medic...

Publication policy or publication bias?

Although ‘‘a large number of studies have appeared in the literature that report associations of low penetrance genetic variants with disease,’’ as suggested in the recent CEBP editorial (1), hardly any of these reports have been translated into solid results by replication studies, at least for the common cancers. To some extent this is inevitable, as false-positive associations are an inheren...

Improving the error rates of the Begg and Mazumdar test for publication bias in fixed effects meta-analysis

BACKGROUND The rank correlation test introduced by Begg and Mazumdar is extensively used in meta-analysis to test for publication bias in clinical and epidemiological studies. It is based on correlating the standardized treatment effect with the variance of the treatment effect using Kendall's tau as the measure of association. To our knowledge, the operational characteristics regarding the sig...
