The receiver operating characteristics (ROC) curve of PFA closure times for the presence of a platelet function disorder. ( A ) PFA ADP: area under the ROC curve (AUC): 0.56 (95% CI 0.50, 0.62). At a threshold of 130 seconds, sensitivity was 19.5% (95% CI 12.6, 30.0) and specificity 86.4% (95% CI 82.4, 89.8). ( B ) PFA EPI: AUC 0.61 (0.55, 0.67). At a threshold of 170 seconds, sensitivity was 44.3% (34.9, 53.9) and specificity was 75.6% (70.8, 79.9). EPI, epinephrine; ADP, adenosine diphosphate; PFD, platelet function disorders.
