RPP rate pressure product = SBP × HR/100, TP total power of HRV, SDNN standard deviation of normal to normal interval, RMSSD square root of the mean of the sum of the squares of the differences between adjacent NN intervals, TG triglyceride, HDL-C high density cholesterol, TC total choleterol, LDL-C low density cholesterol, AIP atherogenic index of plasma = log₁₀[TG/ HDL-C]

p < 0.05 was considered significant
