(A) This figure shows a linear relationship between the Δ[HbT] during the 60mmHg thigh cuff occlusion and the non-diabetic PAD patients’ ABI readings. This suggests that VOTI can differentiate the severity of PAD similar to the ABI measurement. (B) In diabetic PAD patients there is no relationship between ABI measurement and Δ[HbT] within diabetic PAD patients due to arterial calcification falsely elevating the ABI readings.
