  1. * p−value at significant level that is <0.05, Values mentioned as (Mean ± SD), ANOVA test for continuous variables. Abbreviations: r = correlation coefficient, BMI = Body mass index, WHR = Wasit to hip ratio, WC = Waist circumference, Tpe = T peak to T end, VLF = Very low frequency, LF = Low frequency, HF = High frequency, LF(nu) = Low frequency in normalised units, HF(nu) = High frequency in normalised units, SD = Standard Deviation, AVRR = Average RR interval, MEDRR = median RR interval, SDRR = Standard deviation of RR intervals, SDSD = standard deviation of differences between adjacent RR intervals, RMSSD = square root of the mean squared differences of successive RR intervals, Prr50 = percentage of adjacent RR differing by more than 50ms.
