Figure.. Receiver Operator Characteristic Curve for Plasma D-Dimer Concentrations in μg/mL
The receiver operator characteristic curve of plasma D-dimer concentration to classify pulmonary embolism diagnosed by computed tomographic pulmonary angiography at all values of plasma D-dimer in micrograms per milliliter is presented. The performance characteristics at all observed D-dimer concentrations (blue dots), a smoothed, parametric estimation function (solid line), and an uninformative hypothetical test (dashed line) are presented. AUC indicates area under the curve.
