HRV parameters for healthy controls versus tinnitus patients.

HRV parameter	Healthy controls	Tinnitus patients	𝑃 value
TP (ms^2)	7.49 ± 0.99	6.92 ± 1.14	0.020*
VLF (ms^2)	6.37 ± 0.92	6.09 ± 1.21	0.256
LF (ms^2)	5.98 ± 1.19	5.54 ± 1.27	0.114
HF (ms^2)	6.41 ± 1.19	5.13 ± 1.43	0.000**
LF/HF	0.94 ± 0.11	2.48 ± 3.47	0.008**

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 independent sample 𝑡-test. 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.
