From: Combination of pulse volume recording (PVR) parameters and ankle–brachial index (ABI) improves diagnostic accuracy for peripheral arterial disease compared with ABI alone

Figure 4

Comparison of the sensitivity between %MAP and UT according to different grades of stenosis. %MAP shows higher sensitivity for detecting grade 3 and 4 stenosis than UT, whereas UT shows higher sensitivity for detecting mild stenosis of grade 2 than %MAP. ABI, ankle–brachial index; %MAP, percent mean arterial pressure; UT, upstroke time.
