NI = non-infected; IND = indeterminate form; # Data published in [44]; * Mean values calculated from data obtained in previous studies for Selenium (Se, ng/mL) [23] and Tumor Growth Factor (TGF, ng/mL) [26] in CD patients from Rio de Janeiro. CD = Chagas disease, ECG = electrocardiogram, LVEF = left ventricular ejection fraction, CCC = Chronic Chagas Disease Cardiomyopathy.
