“Control” refers to the number of the subjects diagnosed without PVD by the reference method
“Patient” refers to the number of the subjects diagnosed with PVD by the reference method
^aDenotes the number of the limbs used in the study and not the number of subjects
^bComparison between limb segments and not control/patients
