Baseline cardiovascular autonomic study with Type 2 diabetes.

	No CAN (n = 59)	CAN (n = 51)	F†	P-value†
Composite Autonomic Scoring Scale	0.7 ± 0.4	2.9 ± 1.3	119.3	<0.0001***
HR_DB (beats/min)	8.3 ± 4.7	4.3 ± 2.6	46.2	<0.0001***
Valsalva ratio	1.3 ± 0.1	1.2 ± 0.1	22.5	<0.0001***
Baroreflex sensitivity	1.6 ± 0.9	0.9 ± 0.8	13.9	<0.0001***

Data are presented as means ± standard deviations or n (%). ^∗P < 0.05; ^∗∗P < 0.01; ^∗∗∗P < 0.001. Parameters of cardiovascular autonomic study were compared by ANCOVA after controlling for age. F^† and P^† represent the comparison between CAN vs.no CAN group. n, number of cases; HR_DB, heart rate response to deep breathing; CAN, cardiac autonomic neuropathy.
