Multivariate logistic regression results for risk of autonomic nervous parameters on PGC among DM patients

Variable	Adjusted gender, age, beta-blockers		Adjusted gender, age, CAD, beta-blockers, hypertension
	OR (95% CI)	P value	OR (95% CI)	P value
SDNN (ms)	1.018 (1.007–1.030)	0.001	1.018 (1.007–1.030)	0.001
SDANN (ms)	1.018 (1.007–1.030)	0.001	1.018 (1.007–1.030)	0.001
VLF (ms)	1.053 (1.008–1.099)	0.019	1.054 (1.009–1.100)	0.017

PGC poor glycaemic control group, DM diabetes mellitus, CAD coronary artery disease, OR odds ratio, Cl confidence interval, SDNN standard deviation of NN intervals, SDANN standard deviation of all 5-min average NN intervals, VLF very low frequency
