GRADE is a common, sensible and transparent approach to grading quality (or certainty) of evidence and strength of recommendations. You can find information and tools related to GRADE and you can also access a free web application - GRADEpro GDT - which helps you to do a GRADE evaluation to include in a systematic review or in a guideline which can be found here. 

Risk of Bias – the risk of a systematic error or deviation from the truth, in results or inferences – can be assessed by different instruments according to how the trial was designed. You can access all resources related to Risk of Bias created by or in collaboration with Cochrane. It includes full guidance, cribsheets, templates and excel tools for Risk of Bias 2, ROBINS-I and RoB ME. 


Epistemonikos - with over 100,000 systematic reviews – is the world's largest database of reviews. You can often access a short summary of the reviews. The reviews included in this database does not have to be systematic in their approach and does not always include Risk of Bias or evaluate how certain the evidence is. This requires a more advanced knowledge about review-methodology to be able to use the reviews in decision-making.  

Catalog of Bias 

The Catalogue of Bias Collaboration provides a comprehensive list of biases that can be present in medical research. The entries are a work in progress and describe a wide range of biases – outlining their potential impact in research studies with examples of where bias has occurred before. The aim is to better understand the persistent presence, diversity, and impact of biases.
