The remaining 10 (37%) were observational studies, for example, cross-sectional (Abdi et al, 2015a;Dong & Branscum, 2019;Ekúndayò et al, 2020;Nazari et al, 2019;Ott et al, 2015;Romain et al, 2018;Saghafi-Asl et al, 2020), cohort (Kite et al, 2018), longitudinal (Choo & Kang, 2015), and retrospective (Silberman et al, 2020). Meanwhile, the minimum duration of the included studies was less than three months (Tucker et al, 2019;Griffin et al, 2018;Hales et al, 2016;Powers et al, 2019;Sanaeinasab et al, 2020;Spurrier et al, 2018;Vandelanotte et al, 2018;Wright et al, 2020) and the maximum was 24 months (Johnson & Annesi, 2017).…”
