Table 4. Accuracy of FoCUS versus Standard Echocardiography in patients with Chagas disease from the Sami-Trop cohort.

Variables	Sn	Sp	PPV	NPV	Ac
LV dilatation	0.84 (0.75–0.90)	0.94 (0.91–0.95)	0.70	0.97	0.92
LV dysfunction	0.81 (0.71–0.88)	0.94 (0.91–0.95)	0.68	0.97	0.92
RV dilatation	0.46 (0.20–0.75)	0.99 (0.97–0.99)	0.60	0.98	0.98
RV dysfunction	0.37 (0.21–0.56)	1.0 (0.99–1.0)	1.0	0.95	0.96
LV apical aneurysm	0.11 (0.02–0.28)	1.0 (0.99–1.0)	1.0	0.94	0.94

LV = left ventricle; RV = right ventricle; Sn = sensitivity; Sp = specificity; NPV = negative predictive value; PPV = positive predictive value; Ac = accuracy.
