Comparison of the effectiveness of virtual reality and chewing mint gum on labor pain and anxiety: a randomized controlled trial

Table 3 Comparison of mean scores of mothers’ anxiety in three groups of virtual reality, chewing gum and control

Time	Variable	virtual reality	Control	chewing gum	P value
Time	Variable	Mean ± SD	Mean ± SD	Mean ± SD	P value
Dilatation 4-5 cm	anxiety before intervention	40.41 ± 6.32	42.45 ± 4.97	39.77 ± 6.38	P = 0.185* F = 1.720
	anxiety immediately after the intervention	38.32 ± 6.44	44.03 ± 4.90	37.48 ± 6.65	P = 0.000 Df = 2**
	anxiety 30 min after intervention	38.90 ± 6.12	48.48 ± 5.34	38.09 ± 5.84	P = 0.000* F = 30.957
Dilatation 7-8 cm	anxiety before intervention	43.70 ± 5.67	52.19 ± 5.38	42.16 ± 4.84	P = 0.000* F = 32.048
	anxiety immediately after the intervention	40.77 ± 6.74	54.25 ± 5.88	38.90 ± 5.25	P = 0.000* F = 60.545
