 Each of the clusters contains synonymous terms as well as term-adjacent phrase combinations which are in turn used to refine or broaden the search scope to best encapsulate each respective cluster, based on the above definitions.
 
 The search protocol then follows a three-staged process of execution: identification, screening and extraction.

 While the resulting study pools could be screened for in multiple languages, the search queries themselves are passed to the databases in English-language only.
 Relevant results are then complemented through the adoption of a 'snowballing' technique,
 in which an array of identified adjacent published reviews is analysed for their reference lists to find cross-references of potentially missing literature and in turn add those to the pool of studies.

+The predominant amount of literature is based on white literature, with only a marginal amount solely published as grey literature.
 This represents a gap which seems reasonable and not surprising since the database query efforts were primarily aimed at finding the most current versions of white literature.
 Such a stark gap speaks to a well targeted identifaction procedure, with more up-to-date white literature correctly superseding potential previous publications.

 Another reason could be the actual implementation of different policy programmes which are then equally not captured by existing term clusters.
