Table 2.
Sample characteristics separated for the three groups: Verum stimulated participants (VNS), sham stimulated participants (Sham), and participants assigned to the control group (Control), who did not perceive any stimulation.
| VNS | Sham | Control | statistics | |
|---|---|---|---|---|
| N (females) | 25 (14) | 25 (14) | 25 (13) | Χ 2(2) = 0.948 |
| Age (SD) | 24.9 (3.6) | 24.3 (2.7) | 24.6 (3.6) | p = 0.831 |
| Aware | 19 | 21 | 17 | p = 0.405 |
| Stimulation intensity [mA] (SD) | 1.2 (1.1) | 1.0 (0.6) | — | p = 0.338 |
| Stimulation rating (SD) | 6.9 (0.7) | 6.8 (1.6) | — | p = 0.739 |
| US intensity [mA] (SD) | 2.0 (1.6) | 2.7 (1.7) | 2.3 (1.6) | p = 0.393 |
