A database search string (see Appendix 1) was created following a number of iterations that was tested for the number and relevance of their results. The aim was to achieve a balance between the number of relevant documents provided in the search output (and the filtering effort this implied) and certainty that no key documents were excluded. The search was conducted in the months between February and April 2017 and a list of results across databases was compiled to be filtered and reviewed. A small number of additional documents, suggested by experts and interviewees, were incorporated later in the review process where relevant (see Step 8 in Table 3 below). Filtering and initial review The screening and filtering of the search results following the JWEG guidance included a multiple step approach with each step of the process being clearly documented and presented in Table 3.
