Figure 1

ROC curve of QTc for discriminating DNS by ECG recording performed within 6 hours after CO exposure. The area under ROC (AUC) was 0.729 (95% CI: 0.660–0.791). The best cut-off point was 471 ms with a sensitivity of 53.3%, a specificity of 85.1%, a positive predictive value of 23.5%, and a negative predictive value of 95.5%.
