Evidence syntheses are literature studies that that are carried out according to a predefined, systematic and explicit method.
Evidence syntheses include systematic reviews and scoping reviews. What they have in common is that they aim to identify all relevant research that answers a clearly defined question.
In these pages you will find information about systematic reviews and other evidence syntheses. However, they are not intended as a complete introduction and guidance on how to produce evidence syntheses. We recommend that anyone who plans to conduct an evidence synthesis familiarize themselves with the methods described in handbooks (e.g. Cochrane Handbook or JBI Manual) and reporting standards such as PRISMA.
Systematic reviews and other evidence syntheses require systematic literature searches. If you are a researcher or PhD fellow at the University of Oslo or Oslo University Hospital and are conducting an evidence synthesis, you can get help from a librarian with expertise in systematic searches.
