vmHRV reactivity
The results of the linear regression analysis revealed no statistically significant effect of stimulation on vmHRV reactivity between the first and second performance of the ESST, F (2,60) = 1.95, p> .05. While our results indicate that participants that received cTBS over the left dlPFC showed less vagal withdrawal/greater vagal activation during the second ESST compared with the first ESST than participants having received iTBS, β = -5.98, SE = 4.19, t (60) = 1.42, p = .16 or sham stimulation, β= -7.64, SE = 4.10, t (60) = 1.86, p = .07, this effect was not significant (see Figure 5). None of the included covariates exerted a significant effect on the change of vmHRV reactivity.
