Figure

Receiver operating characteristic curve comparing performance of thresholds of absolute and relative eosinophilia to trigger automatic reporting of possible trichinellosis. Sn and Sp for the thresholds of absolute eosinophilia examined were 0.5 × 109 (Sn = 1.0, Sp = 0.65), 0.8 × 109 (Sn = 1.0, Sp = 0.71), 1.0 × 109 (Sn = 0.91, Sp = 0.71), 2.0 × 109 (Sn = 0.63, Sp = 0.94) and for relative eosinophilia were 5% (Sn = 1.0, Sp = 0.65), 10% (Sn = 0.88, Sp = 0.71), 15% (Sn = 0.85, Sp = 0.76), and 30% (Sn = 0.36, Sp = 1.0). Sn, sensitivity; Sp, specificity.
