“…When a study reported multiple overall effect sizes (Allen et al, 2008;Eddy et al, 2007;Gerke, 2008;Goossen et al, 2011;Levine et al, 2006;Ringham, 2006), the effect sizes were combined into one effect size that was included in the meta-analysis. When a study reported both overall effect size and subgroup effect sizes, such as gender (Allen et al, 2008;Gall et al, 2016;Glasofer et al, 2007;Goossens et al, 2007;Lourenço et al, 2008;Matheson et al, 2015;Mirch et al, 2006;Neumark-Sztainer et al, 1997Ranzenhofer et al, 2012;Ringham, 2006;Severi et al, 1993;Tzischinsky and Latzer, 2006;Wildes et al, 2010), the overall effect size was used in the overall analysis, while the subgroup effect sizes were only used for moderator analyses.…”
