Comparison of HRV measures low frequency (LF), High frequency (HF), LF: HF Ratio, SDNN and RMSSD.

Parameters	Normal Controls	Depression Patients	p-value
	(n = 30)	(n = 30)
LF (normalized units)	68.82±1.54	76.13±0.55	†p<0.001***
HF (normalized units)	31.26±1.54	24.09±0.57	†p<0.001***
LF:HF Ratio	2.41±0.15	3.23±0.09	† p<0.001***
SDNN (ms)	50.90±5.12	58.70±6.40	0.345†
RMSSD (ms)	35.40±2.55	35.40±2.80	0.999†

Data expressed in Mean and Standard error of mean,***p<0.001 is considered as very highly significant, p>0.05 is considered as not significant, ^†Unpaired t-test.
