Table 4

Predictors for overall mortality using multivariate forward Cox proportional hazards model.

Parameters	Multivariate (forward)
	Hazard ratios (95% CI)
ΔAoAC (per 1 unit)	1.183 (1.056–1.327)	0.004
Age (per 1 year)	1.091 (1.060–1.123)	<0.001
Cerebrovascular disease	2.705 (1.099–6.658)	0.030
ABI (per 0.1 unit)	0.826 (0.695–0.982)	0.030
CRP (log per 1 mg/L)	2.566 (1.393–4.727)	0.003
