“…Following quality recommendations (WWC, 2020), all studies except for two (Lavik, 2014;Lewandowski, 2011) met standards-with or without reservations-for minimum number of data points per phase and minimum number of phases. In most studies, 24 studies (57%), data collection was interrupted (i.e., no data were collected) during intervention, and baseline performance was compared with a postintervention phase (Ahn, 2017;Asaro-Saddler, 2014;Asaro-Saddler & Bak, 2012;Asaro-Saddler & Saddler, 2010;Bishop et al, 2015;Cerar, 2012;Dunn, 2012Dunn, , 2015Dunn & Miller, 2016;Evmenova et al, 2016;Garwood et al, 2019;Good, 2019;Hashey, 2015;Hoover et al, 2012;Hough et al, 2012;MacArthur & Philippakos, 2010;McKeown et al, 2015;Mong Cramer & Mason, 2014;Mourgkasi & Mavropoulou, 2018;Nordness et al, 2019;Ray et al, 2019;Saddler, 2006;Shen & Troia, 2018;Werunga, 2018).
