Developing the methodology

The Expert Panel's work in developing the Second Expert Report, was based on 20 specially commissioned systematic literature reviews (SLRs).

Methodology Task Force

These SLRs were conducted according to a common, detailed specification, following recommendations made by a special Methodology Task Force.

The Methodology Task Force drew on the accumulated experience of existing techniques to develop a unique new process. The methodology is described in the SLR Specification Manual which contains the instructions for conducting the systematic reviews.

Systematic Literature Review Centres

Scientific centres were invited to bid for the work of conducting the systematic literature reviews and WCRF International contracted with nine institutions in Europe and North America – the SLR Centres.

Using the SLR Specification Manual to plan and undertake their work, the SLR Centres began the task of reviewing the huge numbers of scientific papers. External Peer Reviewers reviewed protocols for the work and final reports (SLRs).

Independence

The independence of the SLR Centres and the Panel was assured by separating the collection of evidence from the business of assessing and judging it.
