2. Comparison of the HRV and HRT data between the two groups.

HRV and HRT parameters Non-OSA (n = 130) OSA (n = 122)
* P < 0.05, difference between OSA and non-OSA group. HF: high-frequency power; HRT: heart rate turbulence; HRV: heart rate variability; LF: low-frequency power; OSA: obstructive sleep apnea; TO: turbulence onset; TS: turbulence slope; VLF: very-low-frequency power.
VLF, Hz 9.2 ± 2.5 12.7 ± 3.0*
LF, Hz 13.4 ± 8.5 20.7 ± 7.5*
HF, Hz 12.2 ± 4.7 9.0 ± 3.5*
LF/HF 1.4 ± 0.5 1.8 ± 0.7*
TO −0.04 ± 0.01 0.04 ± 0.01*
TS 7.6 ± 3.1 4.2 ± 1.5*
