Data are presented as mean±SD.
Unpaired two-tailed t- test was used
BMI: body max index
SSR: sympathetic skin response
HRV: heart rate variability
BP: blood pressure
SDNN: standard deviation of the normal-to-normal interval
SDANN: standard deviation of the average of NN intervals
rMSSD: square root of the mean of the sum of squares of differences of successive NN intervals
PNN50: number of pairs of adjacent NN intervals differing by more than 50 msec in the entire recording divided by the total number of all NN intervals
