The ROC curve of total protein (A) and D-dimer (B) for the diagnosis of PE. A: The AUC was 0.746 (95% Cl 0.611–0.882). The cutoff value of total protein was determined using the ROC curve, and it was found to be 7.0 g/dL or higher. The sensitivity, specificity, and odds ratio for this cutoff value were 72.2%, 80.9%, and 10.5 (95% CI 2.69–48.2), respectively. B: The AUC was 0.696 (95% CI 0.545–0.847). The cutoff value of D-dimer was determined to be 11.8 µg/mL or higher. The sensitivity, specificity, and odds ratio for this cutoff value were 72.2%, 66.0%, and 4.90 (95% CI 1.35–20.9), respectively. AUC = area under the ROC curve, Cl = confidence interval, ROC = receiver operating characteristic.
