	Time	−1.38 (1.01; −3.36 to 0.60)	−1.36 (25)	.19	0.069
	Contrast 1a: passive versus (active and VRb)	5.12 (2.10; 1.01 to 9.23)	2.44 (25)	.02c	0.193
	Contrast 2d: active versus VR	2.30 (2.65; −2.90 to 7.50)	0.87 (25)	.39	0.029

	Contrast 1: time×passive versus (active and VR)	1.66 (2.04; −2.35 to 5.66)	0.81 (25)	.43	0.026

^aContrast 1 compares the pooled interventions (virtual reality and active control) with the passive control group.

^bVR: virtual reality.

^cItalics indicates significant values.

^dContrast 2 compares both intervention groups (virtual reality and active control).
