Assessment of Diabetic Autonomic Nervous Dysfunction with a Novel Percussion Entropy Approach

Table 4

Multivariate linear regression analysis for percussion entropy index (PEI), LHR, and SSR for all subjects (n = 108).

	PEI						SSR			LHR
	B-Coef	β	p	B-Coef	β	p	B-Coef	β	p	B-Coef	β	p
Variable
FBS (mg/dL)	0.824	0.123	0.012	0.825	0.053	0.032	0.841	0.096	0.022	0.826	0.042	0.853
HbA1c (%)	0.654	0.714	<0.001	0.702	0.156	<0.001	0.734	0.037	0.041	0.724	0.129	0.566

B-Coef: regression coefficient; β: standardized coefficient; FBS: fasting blood sugar; HbA1c: glycated hemoglobin; PEI: percussion entropy index; : small-scale multiscale entropy index (mean value of sample entropy from time scale from 1 to 5); SSR: Poincaré index (SD1/SD2 ratio); LHR: low- to high-frequency power ratio.
