“…This left 18 publications reviewed in full, 10 articles were excluded (Bayar et al, 2008;Chawla and Arora, 2013;Cherrier et al, 2013;Karvinen et al, 2007;Lester, 2012;Månsson et al, 1998;Modh et al, 2014;Shih and Porter, 2011;Weinstein Dunn, 2015;Williams-Cox, 2004) with reasons because they did not meet the inclusion criteria, see Figure 1. This left 8 articles which fully met the inclusion criteria, of which two articles reported on the same study (Mohamed et al, 2014;Mohamed et al, 2016). In total, there were 6 exploratory qualitative studies (Ali and Khalil, 1989;Cerruto et al, 2014;Fitch et al, 2010;Månsson et al, 1991;Mohamed et al, 2014;Mohamed et al, 2016;Nordström et al, 1992;Perlis et al, 2014) and one feasibility RCT study (Ali and Khalil, 1989) see Table 3 for an overview of the studies included (Supplementary Table 5 contains full data extraction of primary studies).…”
