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

aABI categories were defined as ab-ABI (<1.0 or >1.4) and nl-ABI (1.0≤ABI≤1.4). bModel 1 was adjusted for age and sex and model 2 was further adjusted for cigarette smoking, body mass index, number of diseased vessels, and underlying disease. cMACE included disease progression, repeated revascularization, and all-cause mortality. dDisease progression was defined as stenosis >30% or occlusion of any coronary artery that has newly appeared on the latest coronary angiography. eRepeated revascularization was identified as stenosis >50% on coronary angiography or stenosis <50% with a correlated symptom.
