Correlation between the study parameters at T2 (after noxious stimuli).

Correlation between study parameters	r-value	P-value
HR and SBP	0.5	0.05
HR and RE	0.31	0.04*
HR and RE-SE	0.08	0.27
HR and PI	−0.12	0.2
SBP and PI	−0.005	0.9
SBP and RE	0.32	0.04*
SBP and RE-SE	0.12	0.23
RE and PI	0.18	0.19
RE and NRI	0.23	0.06
RE-SE and PI	−0.12	0.23
RE-SE and NRI	0.13	0.2

^*P<0.05 is considered statistically significant. ^#P<0.001 is considered highly significant. HR: Heart rate, RE: Response entropy, SE: State entropy PI: Perfusion index, NRI: Nociceptive response index, SBP: Systolic blood pressure
