Relationship between ABI and microalbuminuria and blood glucose control

Variable		Microalbuminuria		ABI
		(−)	(+)	≤0.90	>0.90
Fasting blood glucose level	≤7.2 mmol/L	15	4	1	17
	>7.2 mmol/L	17	26	14	29
OR, 95% CI, P		P = 0.004		P = 0.021
		OR = 5.7		OR = 8.6
HbA1c level	<7 %	21	12	5	28
	≥7 %	11	18	10	19
OR, 95% CI, P		P = 0.043		P = 0.048
		OR = 2.8		OR = 2.9

ABI, ankle–brachial index; CI, confidence interval; OR, odds ratio.
