SBU compiles scientific uncertainties in healthcare. The aim is to draw attention to questions which require further research. For certain conditions, such as ADHD, there are many uncertainties. In such cases, it may be important to list in order of priority those uncertainties which are most urgent to investigate.
Evidence gap identifies methods or practices for which no conclusive systematic review of benefits and harms has been published. Gaps in scientific evidence appear on the SBU website to help researchers and granting agencies identify areas that are in need of research or systematic review. An additional objective is to offer healthcare and social service providers a basis for setting priorities.
