In the correlation of carotid angiography and noninvasive testing, what was the specificity value?

In the context of carotid angiography and noninvasive testing, specificity refers to the ability of a diagnostic test to correctly identify patients who do not have the disease, which in this case is carotid artery disease. A specificity value of 94.6% indicates that this particular noninvasive testing method is very effective at accurately ruling out individuals who do not have significant carotid artery stenosis when compared to the gold standard of carotid angiography.

A high specificity value is crucial in clinical settings as it helps reduce the number of false-positive results. This allows for a better allocation of healthcare resources, as patients who truly do not have the disease can be reassured and spared from unnecessary interventions or further invasive testing. The provided specificity value signifies a strong capacity of the noninvasive test to confirm healthy findings, aligning closely with outcomes observed in actual angiographic evaluations.

In summary, the specificity value of 94.6% highlights the reliability of the noninvasive testing method in conjunction with carotid angiography for accurately identifying patients without the disease.
