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 3

Comparison of sensitivity between ABI alone and the combination of ABI, %MAP and UT according to different grades of stenosis. The combination of the ABI, %MAP and UT shows higher sensitivities than ABI alone for detecting every grade of stenosis. ABI, ankle–brachial index; %MAP, percent mean arterial pressure; UT, upstroke time.
