Comparative effect of deliberate hypotensive anesthesia using nitroglycerine vs. phentolamine on event related potentials and cognitive functions in patients undergoing septoplasty: a randomized controlled trial

Table 3 Percent of change in PALT and BVRT in both Nitroglycerine and Phentolamine groups

	Nitroglycerine group (n = 40)	Phentolamine group (n = 40)	P- value
Percent of change in PALT [Median (IQR)]	-3.85% (-10.83%-5.41%)	-7.96% (-12.2%- 6.16%)	0.689
Percent of change in BVRT [Median (IQR)]	-6.07% (-11.6% -8.33%)	0% (-16.67%- 8.33%)	0.675

Values are expressed as median (Q1-Q3)
PALT: Paired Associate Learning Test, BVRT: Benton Visual Retention Test
Mann-Whitney test was used for comparison between Nitroglycerine and Phentolamine groups
P-value > 0.05 is considered in-significant
