What percentage of the true negatives were correctly identified as negative in the carotid testing?

The percentage of true negatives correctly identified as negative in carotid testing reflects the specificity of the test, which indicates the ability of the test to correctly identify individuals who do not have the condition being tested for. When looking for the correct answer, it’s important to consider that a high percentage signifies a reliable test, meaning it is effective in minimizing false positives.

In this context, a figure like 91% suggests that the test accurately recognized a large proportion of individuals without carotid artery disease as negative. This is crucial in clinical settings as it helps to ensure that healthy individuals are not subjected to unnecessary interventions or treatment.

Higher accuracy percentages in identifying true negatives also contribute to more trust in the overall testing process, as clinicians and patients can feel confident that when the test indicates a negative result, it is indeed reflective of the patient's actual health status.
