Figure 1 shows a study flow diagram. The citations identified by the literature searches (293) enters the flow diagram at the top. These citations are screened by title and abstract, with the number excluded (189) listed in a box to the right. Continuing down the flow diagram, the number of articles retrieved (104) for full-article screening are shown in a box, and then they are screened against the full set of inclusion criteria. Excluded articles (64) exit the diagram to the right and are listed in a box with specific reasons for exclusion. Finally, at the bottom of the diagram the number of included studies (40) is shown.
