      Publications identified through the literature search

After merging the citations from the electronic search of the seven databases and removing duplicates, 4807 studies remained for possible inclusion in the systematic review. Following a review of titles and abstracts, and initial screening of full papers where necessary, 18 studies met the inclusion criteria and were appraised further for methodological quality.

Of the 18 studies assessed for methodological quality, nine were of sufficient quality to proceed to the data extraction (DE) stage. A detailed breakdown of the flow of studies from the initial search strategy to evidence synthesis can be found in Figure 4.1.1.
