Table 2. Odds ratio for poor outcome of groups categorized with ABI and baPWV.

	ABI ≥ 0.9	ABI < 0.9
baPWV ≤ 1870	Group 1	Group 3
	N = 316	N = 21
	1.0 (reference)	5.19 (1.85–15.14)
baPWV > 1870	Group 2	Group 4
	N = 473	N = 51
	1.46 (0.95–2.27)	3.37 (1.63–7.08)

Odds ratio (95% confidence intervals) was calculated with multivariate logistic regression analysis adjusted with age, body mass index, large artery atherosclerosis, National Institute of Health stroke scale on admission, smoking, hypertension, diabetes mellitus and antithrombotic agent, which associated with poor outcome.

ABI, ankle brachial index; baPWV, brachial-ankle pulse wave velocity.
