HRV parameters for healthy controls and acute and chronic tinnitus patients.

HRV parameter	Healthy controls	Tinnitus patients		𝑃 value
		Acute	Chronic
TP (ms^2)	7.49 ± 0.99	6.99 ± 1.23	6.86 ± 1.09	0.063
VLF (ms^2)	6.37 ± 0.92	6.18 ± 1.32	6.01 ± 1.12	0.461
LF (ms^2)	5.98 ± 1.19	5.52 ± 1.36	5.56 ± 1.22	0.288
HF (ms^2)	6.41 ± 1.19^a	5.31 ± 1.34^b	4.97 ± 1.52^b	0.000**
LF/HF	0.94 ± 0.11^a	1.85 ± 2.13^a, b	3.05 ± 4.32^b	0.007*

HRV data were log-transformed prior to statistical analysis. The values given are the mean ± SD. Statistical significance was set at a 𝑃 value < 0.05, using analysis of variance (ANOVA). If there were statistically significant differences between groups, the post hoc test (Duncan) was used to identify them with “^{a, b}”. TP: total power; VLF: very low frequency; LF: low frequency; HF: high frequency; LF/HF: ratio of absolute LF to HF power; *𝑃<0.05; **𝑃<0.01.
