Linear regression analyses examining anxiety and log-transformed salivary cortisol differences pre and post intervention.

Comparison	Model 1a			Model 2b			Model 3b
	β	SE	P valuec	β	SE	P value	β	SE	P value
VRd meditation (n=8) vs audio meditation (n=11, reference group)	3.13	2.82	.28	.04	0.19	.84	–.19	0.23	.43
VR meditation (n=8) vs VR imagery (n=10, reference group)	–1.80	3.34	.59	.04	0.04	.30	–.06	0.07	.38

^aModel 1: difference in pre and post State-Trait Anxiety Inventory-6 anxiety scores reflect measures collected before vs after the interventions at visit 2, controlling for preintervention anxiety levels.

^bModels 2/3: difference in pre and post log cortisol values reflect measures collected before (sample 2) vs after (sample 3/sample 4) the interventions at visit 2, controlling for preintervention logged cortisol levels from sample 2.

^cP values are based on the Wald test, comparing VR meditation to the referent group (audio meditation or VR imagery).

^dVR: virtual reality.
