Table 4.

The median and interquartile range values for variables of time and frequency domain between MetS and nMetS groups.

	Metabolic syndrome						P value
	No			Yes
	N	Median	IQR	N	Median	IQR
ln⁡VLF (ms2/Hz)	50	6.2	5.7–6.8	43	6.2	5.6–7.0	0.697
ln⁡LF (ms2/Hz)	50	5.5	5.0–6.4	43	5.5	4.8–6.3	0.951
ln⁡HF (ms2/Hz)	50	5.4	4.6–5.9	43	5.3	4.5–6.0	0.844

P value using Mann-Whitney U test.

VLF: very low frequency, HF: high frequency, LF: low frequency, and IQR: interquartile range.
