Figure 3. ROC curve illustrating a fair accuracy time duration, using the TTP for the diagnosis of pulmonary hypertension (PAP ≥ 25 mmHg). For the cutoff point of TTP < 127 ms, the accuracy indices are presented above. All of the values are presented with their CI 95% sensitivity: 0.68 (0.51 - 0.82), specificity: 0.68 (0.45 - 0.85), positive predictive value: 0.79 (0.61 - 0.90), negative predictive value: 0.56 (0.36 - 0.73), and area under the curve = 0.746 ± 0.064.
