| http://www.w3.org/ns/prov#value | - The ratio of the left and right ankle pressures to the brachial pressure is the left and right ABI. ABI <0.9 indicates PAD. ABI between 0.5 and 0.9 corresponds to intermittent claudication in the lower limbs, whereas values <0.5 are associated with more severe symptoms such as resting pain, severe occlusion and critical ischemia.
