Change in pre-treatment and posttreatment anxiety scores with respect to Venham's picture test, facial image scale, pulse rate, respiratory rate, and oxygen saturation

Parameters	Group			p value
	Control group	Music distraction group	Aromatherapy group
Venham's picture testa	0.06 ± 1.24	−4.1 ± 1.45	−4.1 ± 2.15	<0.001
Facial image scalea	0.42 ± 1.16	−2.34 ± 1.04	−2.14 ± 1.28	<0.001
Pulse rateb	5 (−4.22)	−9 (−43.17)	−8 (−41.5)	0.0001

Oxygen saturationb	0 (−2.2)	1 (−3.5)	0 (−1.2)	0.005

p < 0.001 is considered significant

^aMean ± S.D, the p value is computed using ANOVA test

^bMedian (Min, Max), the p value is computed using Kruskal–Wallis test
