“…Of these studies, 11 reported higher prevalence estimates as compared to PAHO (Barona-Vilar et al, 2012; Jackson et al, 2010; Jackson et al, 2009; Lucas and Barba, 2009; Paricio-Talayero et al, 2008; Roca et al, 2011) and 6 had similar estimates (El Ghouzzi et al, 2010; Ramos et al, 2012a; Ramos et al, 2012b). For Paraguayan migrants, 3 studies had similar prevalence estimates to countrywide estimates (Ramos et al, 2012a; Ramos et al, 2012b), while 3 were higher (Figure 4) (Avila Arzanegui et al, 2013; Barona-Vilar et al, 2012; Lucas and Barba, 2009). However, it should be noted that one sample that was higher was only based on 6 individuals, and thus was very imprecise (95% CI: 3.0–56.4) (Lucas and Barba, 2009).…”
