“…Therefore, we conducted a systematic review and meta-analysis for the remaining 43 articles. We derived 49 effect sizes for the metaanalysis because five studies (Drukker, Kaplan, Feron, Van Os, & Korebrits, 2010;Fagan & Wright, 2012;Heberle, Thomas, Wagmiller, Briggs-Gowan, & Carter, 2014;Karriker-Jaffe, Foshee, Ennett, & Suchindran, 2009;Pabayo, Molnar, & Kawachi, 2014) reported results separately for male and female participants, and one study (Delany-Brumsey, Mays, & Cochran, 2014) reported results separately for children (ages 5-11 years) and adolescents (ages 12-17 years). Two studies (Goodnight et al, 2012;Santiago, Wadsworth, & Stump, 2011) reported the neighborhood effects on both aggression and delinquency, and one study (Farrell, Mehari, Kramer-Kuhn, & Goncy, 2014) reported outcomes across two time points; thus, we used the combined effects across outcomes and time points.…”
