Values are presented as number (%).

ABI, ankle-brachial index; ab-ABI, abnormal ABI; nl-ABI, normal ABI; MACE, major adverse cardiac events.

^aABI categories were defined as ab-ABI (<1.0 or >1.4) and nl-ABI (1.0≤ABI≤1.4). ^bP-value was determined using the chi-square test. ^cMACE included disease progression, repeated revascularization, and all-cause mortality. ^dDisease progression was defined as stenosis >30% or occlusion of any coronary artery on the latest coronary angiography. ^eRepeated revascularization was defined as stenosis >50% on coronary angiography or stenosis <50% with a correlated symptom.
