Results of Post-Exercise ABI and Exercise TcPO2 in patients with exertional limb symptoms and normal ABI (>0.90). Horizontal line represents the cut-off value (DROP: delta from rest of oxygen pressure) of exercise transcutaneous oxygen pressure measurement (−15 mmHg). Vertical line represents the cut-off value of Post-exercise ABI (ankle-brachial index) decrease (18.5%).
