The objective of the evidence base is to disseminate the best available information to promote the implementation of effective HBV and HCV prevention, testing, and treatment interventions to achieve elimination goals. The evidence base is a repository of systematic reviews on priority topics, such as hepB birth dose and hepatitis action plans. The evidence base is a searchable database of the individual references identified in each systematic review. Synthesis briefs that summarize the key findings and implications of each systematic review are available.
