Table 2.

Overall guideline for the inclusion and exclusion of articles.

Items	Description
Population	The search strategy should not limit the educational groups targeted by the studies (eg, no limitations in terms of gender, age, health, or economic status)
Concept	The search strategy will not discriminate about the underlying educational goal of the games and will be agnostic about the platform used to deliver the games (eg, no limitations on the learning techniques and no limits on software choices)
Context	The search strategy will not limit the inclusion based on the affiliation of authors but will limit the papers to English articles published between January 1985a and December 2018

^aPrevious systematic reviews identified no health education game studies published before 1985.
