The ankle-brachial pressure index (ABPI) or ankle-brachial index (ABI) is the ratio of the blood pressure at the ankle to the blood pressure in the upper arm (brachium). Compared to the arm, lower blood pressure in the leg suggests blocked arteries due to peripheral artery disease (PAD).
Ankle-brachial pressure index (ABPI) assesses peripheral vascular disease. [1] It may however be unreliable in patients with calcified arteries in the calf (often diabetic patients) or those with extensive oedema, in which case toe pressure or Toe-brachial pressure index (TBPI) should be measured to aid in the diagnosis.

"Measurement of ankle blood pressures in a seated position will grossly overestimate the ABI (by approximately 0.3)." If the factor of "overstatement" is less than one, the value is being understated, not overstated. Could it be that what's meant is that the overestimate will be on the order of 30 percent--i.e., 1.3 times what it should be?
Evidence supports the rules as an accurate instrument for excluding fractures of the ankle and mid-foot, reducing the number of unnecessary investigations and length of stay in emergency departments. [3] The original study reported that the test was 100% sensitive and reduced the number of ankle X-rays by 36%. [4]
If adaptations to the environment are made, they should be described in detail and attached to the Barthel index. [ 2 ] The scale was introduced in 1965, [ 3 ] and yielded a score of 0–100 (Mahoney, F.I. & Barthel, D.W., 1965.
The Framingham Risk Score is a sex-specific algorithm used to estimate the 10-year cardiovascular risk of an individual. The Framingham Risk Score was first developed based on data obtained from the Framingham Heart Study, to estimate the 10-year risk of developing coronary heart disease. [1]
