Toe-brachial index and toe systolic blood pressure for the diagnosis of peripheral arterial disease

To (1) estimate the accuracy of TSBP and TBI for the diagnosis of PAD in the lower extremities at different cut-off values for test positivity in populations at risk of PAD, and (2) compare the accuracy of TBI and TSBP for the diagnosis of PAD in the lower extremities.

This is a protocol.
