Results of a Cox Regression Analysis for MACEs.

Variables		Unadjusted HR (95% CI)		p		Adjusted HR (95% CI)		p
Age		1.05 (1.01-1.09)		0.028		1.04 (1.00-1.09)		0.072
Male		0.96 (0.42-2.20)		0.918		1.36 (0.52-3.53)		0.536
Preoperative ABI		0.80 (0.10-6.52)		0.838		0.38 (0.05-3.12)		0.369
ΔABI ≥0.15		0.49 (0.25-0.97)		0.040		0.38 (0.17-0.83)		0.016

ABI: ankle-brachial index, MACEs: major adverse cardiovascular events

Multivariate models were adjusted for age, male gender, and preoperative ABI.
