Association between statistical significance and time to publication among systematic reviews: a study protocol for a meta-epidemiological investigation
INTRODUCTION Many studies have indicated the impact of bias in dissemination and publication in medical research. Existence of such bias among clinical trials has been repeatedly pointed out, but it has not been well studied in the field of systematic reviews (SRs). We therefore aim to investigate whether or not time lag bias and publication bias in SRs based on statistical significance in resu...
متن کاملNo difference found in time to publication by statistical significance of trial results: a methodological review
OBJECTIVE Time-lag from study completion to publication is a potential source of publication bias in randomised controlled trials. This study sought to update the evidence base by identifying the effect of the statistical significance of research findings on time to publication of trial results. DESIGN Literature searches were carried out in four general medical journals from June 2013 to Jun...
متن کاملPublication bias and the chase for statistical significance.
Most published research findings are false according to Ioannidis. As social animals, we are attracted, sometimes irresistibly, towards accepting sensational positive results and inclined to dismiss the negative ones ---which may be just as important. We have also come to believe that the reliability of a result in medical research, including optometry and ophthalmology, should be expressed sol...
متن کاملTime Series Motifs Statistical Significance
Time series motif discovery is the task of extracting previously unknown recurrent patterns from time series data. It is an important problem within applications that range from finance to health. Many algorithms have been proposed for the task of efficiently finding motifs. Surprisingly, most of these proposals do not focus on how to evaluate the discovered motifs. They are typically evaluated...
متن کاملEffect of the statistical significance of results on the time to completion and publication of randomized efficacy trials.
CONTEXT Medical evidence may be biased over time if completion and publication of randomized efficacy trials are delayed when results are not statistically significant. OBJECTIVE To evaluate whether the time to completion and the time to publication of randomized phase 2 and phase 3 trials are affected by the statistical significance of results and to describe the natural history of such tria...
