Clinical probability assessment
in the Prospective Investigation of
Pulmonary Embolism Diagnosis study was standard, sometime ago. . With this scoring system, 66.7% of the patients in the high probability group, 20.5% of the patients in the intermediate- probability group, and 3.6% of the patients in the low-probability group were diagnosed with PE [13].
It could be most reassuring if all the additional accumulated evidence supported your not having had a PE.
