* PAD, peripheral arterial disease.
† Sensitivity, the probability of a positive test result in patients with asymptomatic PAD.
‡ Specificity, the probability of a negative test result in patients without PAD.
§ PVP, probability of asymptomatic PAD given a positive test result.
‖ PVN, probability of no PAD given a negative test result.
