The ankle-brachial index (ABI) is widely used to diagnose subclinical peripheral artery disease (PAD) in the general population, but data assessing its prevalence and related factors in different chronic kidney disease (CKD) stages are scarce.

A trained team collected clinical and laboratory data, performed vascular ultrasounds and measured the ABI.PAD prevalence was higher in CKD than in controls (28.0 versus 12.3
