Results from multiple linear regression analyses with insulin resistance (M value) as dependent variable and body composition (BMI or VAT), age, and LF-to-HF power ratio during long-term HRV entered as independent variables

Dependent variable	Independent variables	Std β	p value
M value	BMI	−0.46	0.001
	Age	0.03	0.81
	Long-term LF to HF power ratio	−0.29	0.040
M value	VAT	−0.35	0.029
	Age	0.06	0.04
	Long-term LF to HF power ratio	−0.31	0.054

Spectral indices are log-transformed. Age and body composition (BMI or VAT) were entered as independent variables

HRV heart rate variability, LF to HF power ratio ration between power of the low frequency and high frequency component, BMI body mass index, VAT visceral adipose tissue
