Accuracy of ankle-brachial index in screening for peripheral arterial disease in people with diabetes.

ABSTRACT: Although the ankle-brachial index (ABI) presents overall satisfactory accuracy, its sensitivity in the context of screening strategies does not ensure the detection of all individuals with peripheral arterial disease (PAD), especially in clinical situations where there is calcification of the arterial media layer. This study evaluated the accuracy of ABI in screening PAD among individuals with diabetes mellitus (DM) in a community setting. An observational study included only individuals with DM. ABI measurement was performed, and the lower limb duplex ultrasound (DU) was used as the reference standard for PAD diagnosis. Sensitivity, specificity, positive and negative predictive values (PPV and NPV), and positive and negative likelihood ratios (LR+ and LR-) of ABI were assessed. The analys
