In a binary stepwise logistic regression analysis excluding patients with an ABI > 1.3, only total cholesterol (β = 0.01, p = 0.02) and fetuin-A (β = -5.99, p = 0.03) proved to be independent predictors of an ABI < 0.9, while age, gender, HbA1c, and glomerular filtration rate were not sig-nificantly associated with PAD. This evidence concerns the gene AHSG and peripheral arterial disease.
