“…For example, articles which examined RSA withdrawal and children’s health outcomes such as obesity (Graziano, Calkins, Keane, & O'Brien, 2011), immune response (Cacioppo, 1994), asthma (Miller, Wood, Lim, Ballow, & Hsu, 2009) or epilepsy (Harnod et al, 2008) were excluded. We also excluded articles examining the link between RSA withdrawal and sleep (El-Sheikh & Buckhalt, 2005), substance exposure (Hickey, Suess, Newlin, Spurgeon, & Porges, 1995; Sheinkopf et al, 2007) or parenting factors (Blandon, Calkins, Keane, & O'Brien, 2010; Calkins & Johnson, 1998; Mills-Koonce et al, 2009; Oosterman & Schuengel, 2007). Articles that solely examined the stability of RSA withdrawal (Bornstein & Suess, 2000; El-Sheikh, 2005), or changes in RSA withdrawal associated with treatment (Beauchaine, Gartner, & Hagen, 2000; Graziano, Bagner, Sheinkopf, Vohr, & Lester, 2012) were also excluded.…”
