  • * 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.
