This section contains all the reports produced by HEN as syntheses of the best available evidence in response to policy-makers’ questions.
When the evidence conflicts, the report outlines the context and level of the debate. Each report goes through three reviews:
- an initial review by the HEN team;
- an internal and external peer review; and
- quality control by the HEN team.
The evidence reports published on this web site are commissioned works and the contents are the responsibility of the authors. They do not necessarily reflect the official policies of WHO/Europe or HEN. All reports undergo rigorous external review, as well as internal review.
