  1. Data are n (%), means ± SD (standard deviation), median value (25, 75 percentile)
  2. PWV pulse wave velocity, Log logarithmic value, HF high frequency, LF low frequency, NN normal-to-normal RR interval, SDNN standard deviation of all normal-to-normal RR intervals, r-MSDD square root of the mean of the squares of successive differences between adjacent NN intervals, BRS baroreflex sensitivity
  3. *p values for comparisons between groups by Mann–Whitney U test
  4. **p values for comparisons between groups by Independent samples t-test
