According to James et al (2016), "systematic mapping does not attempt to answer a specific question as do systematic reviews, but instead collates, describes and catalogues available evidence (e.g. primary, secondary, theoretical, economic) relating to a topic or question of interest."
Other names used for Mapping Reviews: Mapping Evidence Review, Mapping Study, Mapping Review, Mapping Exercise, Systematic Map
