Clinical presentation and early predictors for poor outcomes in pediatric myocarditis: A retrospective study

Figure 3 Area under receiver operating characteristic curve of N-terminal pro-brain natriuretic peptide for determining left ventricular ejection fraction < 30%. N-terminal pro-brain natriuretic peptide presented a high diagnostic accuracy for severe left ventricular systolic dysfunction on echocardiography with an area under curve of 0.931 (95%CI: 0.858-0.995, P < 0.001). The best cut-off point was 2000 pg/mL, with a sensitivity of 90%, specificity of 81%, positive predictive value of 60%, and negative predictive value of 96%.
