Description of the methods used for determination of the ankle-brachial index (ABI)

Method of ABI determination

Procedure (nominator in the ABI calculation)


highest systolic pressure (tibial anterior/posterior artery)


lowest systolic pressure (tibial anterior/posterior artery)


only systolic pressure of tibial anterior artery


only systolic pressure of tibial posterior artery


after exercise (tibial posterior artery only)

The blood pressure measurements were performed on each leg as described in the methods section. The denominator in all calculations was the average of the right and left brachial arterial pressure (unless discrepancy of ≥10 mmHg, which led to the use of the higher pressure).
