Evolution over time of mean and standard deviation (SD) of the primary and secondary outcomes in the CTR group and in the VRH group.
| CTR (n = 15) | VRH (n = 18) | Time | Effect size | |||||||
|---|---|---|---|---|---|---|---|---|---|---|
| Questionnaires (Mean ± SD) | T0 | T1 | T2 | T3 | T0 | T1 | T2 | T3 | p-value | η2 |
| Anxiety (0–10, NRS) | 2.9 ± 3 | 3.13 ± 3 | 2.3 ± 2.7 | 0.8 ± 1.4 | 3 ± 2.5 | 4 ± 3.3 | 2.8 ± 3.1 | 1.1 ± 2 | <0.001 | 0.3 |

The p-values and effect size concern the time effect only. T0 = screening by phone call; T1, pre-CTR/VRH; T2, post-CTR/VRH; T3, post-Tf-Rc; CTR, control; VRH, Virtual reality hypnosis; NRS, Numerical Rating Scale; NA, non-applicable; * the statistical comparison has been tested with a Mann–Whitney U test.
