One in five. 6.3% vs 20%.

I googled and saw the test implies measuring arterial blood pressure in an arm and in a leg in about the same time and then dividing systolic pressure in ankle vs arm. Since you cannot hear with a stethoscope the blood pulsating in your leg (like you can in the arm) the artery being smaller and deeper you have to use a small portable vascular doppler device that translates blood flow into sound.
But then i remembered years ago i played with my automated BP monitor and measured my BP at ankles just to see if i cam read anything and i could. I don't remember any difference between the arm readings and the ankle readings back then and i thought that was an alternate way to measure BP.
And then i had this idea and googled again and mr. google told me that i can do the ABI test with a regular automated BP monitor (though they also have specialized machines that probably include several monitors to measure it simultaneously in all locations),
Which i performed and the readings came in the middle of normal range (though not the same as 20 years ago), with about 5% consistent difference between left and right leg, doing the test repeatedly, (left foot being bluer in color than right).
