5.1 The Catalog of Bias
The Catalog of Bias (Catalog of Bias Collaboration 2024) is a collaborative project mapping all the biases that affect health evidence. The catalog provides:
- Clear definitions and explanations of various biases
- Real-world examples from health research
- Directed acyclic graphs (DAGs) illustrating bias mechanisms
- Guidance on study design and analysis to prevent or minimize bias
The catalog is an invaluable resource for researchers, clinicians, policymakers, journalists, and the public who seek to better understand threats to research validity.
