Frontal asymmetry | Sham taVNS (n = 22) (Mean ± SD) | Active taVNS (n = 20) (Mean ± SD) | Unadjusted effects coef. (95% CI, p-value) | Adjusted effects* coef. (95% CI, p-value) |
|---|---|---|---|---|
Delta | -0.025 ± 0.016 | 0.016 ± 0.012 | 0.042 (0.001 to 0.089; 0.045) | 0.045 (0.001 to 0.089; 0.046) |
Theta | 0 ± 0.001 | 0.002 ± 0.004 | 0.002 (-0.013 to 0.017; 0.835) | 0.002 (-0.014 to 0.018; 0.835) |
Difference Delta-Theta | -0.025 ± 0.014 | 0.015 ± 0.012 | 0.040 (0.002 to 0.078; 0.041) | 0.042 (0.001 to 0.083; 0.044) |
