“…This idea arose in the 1980s in studies featuring statistical meta-analysis (Glass et al, 1981) and meta-ethnography (Noblit & Hare, 1988). Although the literature review as a form of study has been continuously developed over many years (Boland, Cherry, & Dickson, 2017;Bolin, 2012;Shadish & Lecy, 2015;Sheble, 2017), the systematic literature review is "still a young and rapidly developing field of study and methods of reviewing have not been developed for all areas of science" (Gough, Oliver, & Thomas, 2017, p. 9). There are still many challenges to be overcome (Dickersin, 2015;Oakley et al, 2005) such as conceptual and methodological challenges, resource constraints, the constraints related to the use of reviews, and broader political challenges (Gough, Oliver, & Thomas, 2017).…”
