HRV parameterHealthy controlsTinnitus patients value

TP (ms2)7.49 ± 0.996.92 ± 1.140.020*
VLF (ms2)6.37 ± 0.926.09 ± 1.210.256

HRV data were log-transformed prior to statistical analysis. The values given are the mean ± SD. Statistical significance was set at a value < 0.05, using independent sample -test. TP: total power; VLF: very low frequency; LF: low frequency; HF: high frequency; LF/HF: ratio of absolute LF to HF power; * ; ** .
