Variable	Group S (n = 50)	Group P (n = 50)	P-value
Age (years)	6.9 ± 2.6	6.2 ± 2.2	0.11
Gender male Female	28(56%) 22(44%)	24(48%) 26(52%)	0.55
Weight (kg)	20.9 ± 7.5	19 ± 6.2	0.13
Duration of surgery (min)	57.8 ± 2.9	57.7 ± 2.6	0.60
Duration of anaesthesia (min)	67.9 ± 3.5	68.3 ± 3.3	0.09

Data were expressed as mean ± standard deviation or number (percentage). Kg stands for kilogram.

S: Sevoflurane group P: propofol group (p value < 0.05 was assumed statistically significant).
