The Catalogue of Bias (CoB), is a digital resource for clinicians, students, researchers, investigators, and consumers of health evidence. As of posting this blog, the catalogue has 49 published biases.
Randomized controlled trials (RCTs) can be subject to different kinds of bias. Read about different sources of bias in this blog and how much the magnitude of effect can be changed by the presence of bias.
The EU Trials Tracker, devised by the EBM DataLab at the University of Oxford, tracks which trials on the European Union Clinical Trials Register (EUCTR) have reported their results within a year of completion. Learn more about this tracker and how you need to take action.
Publication bias remains a problem in health research. This blog by Andrés explores the issues we face and provides detail of the initiatives designed to address the problem.
Debiasing is about trying to account for and eliminate the influence of biases on our decision-making. This blog discusses effective debiasing techniques.
This blog takes a detailed look at the issue of attrition bias (bias that can arise when participants drop out of a study). It also describes measures that can be taken by researchers to minimize this bias (including different types of statistical analyses).
This blog discusses the problem of confirmation bias: our tendency to favour answers that confirm ideas and beliefs that we already have. It also discusses two possible solutions to this problem: 1) referring to systematic reviews, which take account of ALL the available evidence and 2) actively seeking out information which may challenge our preconceptions.
A brief overview of the concept of bias and what it means. This blog also describes 2 particular types of bias that are perhaps less well known to students.
Katherine Stagg explores the impact of language bias and how the language of publications can affect our evidence base.
Does industry sponsorship of research inevitably lead to bias? And does this bias extend to government advice and policy?
Publication bias is generally ascribed to failure by researchers to submit studies for publication. This current study aims to further evaluate whether the editorial and peer review process also contributes to publication bias.
This tutorial teaches you about one of the biggest enemies of strong evidence in clinical research – bias, as well as measurements and outcomes in the clinical trial.
Statistically funny – the blog that combines cartoons, humour, and demystifying evidence-based medicine.
Empowering the patient to take an active role in their health decision-making is a vital aspect of evidence-based healthcare. Explore more on this topic in this latest blog.
Are the methods we use to measure academic success driving authors to prioritise quantity over quality? How does the presence of predatory journals further influence behaviour within the scientific publishing world?
