Data from NHANES which is representative of the US population is utilized on more than 6000 individuals and used to predict presence of PAD
Peripheral arterial disease (PAD) doubles your chance of death. Measurement of a ratio between the ankle and arm pressure also known as the ankle brachial index (ABI) is a screening test. Data from NHANES (a stratified ongoing sample of the US population) with available ABI data is used Random Forest Machine learning with 100 trees on a dataset of more than 6000 yielded the predictive model Given preponderance of patients without PAD the model is better suited to predicting the absence of PAD You can enter you age, your guess of whether you have PAD or not and your maximal calf circumference Maximal calf circumference is measured in Cm by moving the measuring tape up and down the calf while seated to find the largest part. The results are output from a mathematical model and not a diagnostic test by any means Medical advice should be sought from your doctor and this service by no means claims to be a diagnostic test
