LF-low frequency; HF-high frequencies; LF/HF the ratio of LF-HF power; LF_nu-Normalized power in LF band, HF_nu-Normalized power in HF band, a derived index that is computed by dividing HF by some suitable denominator representing the total relevant power; SDNN -the standard deviation of normal RR intervals; r-MSDD- the square root of the mean of the squared differences between adjacent normal RR intervals; HRV- heart rate variability. All outcomes were log transformed.
